Product Overview
49164395 is the primary intake air filter element for Ingersoll Rand rotary screw air compressors, manufactured to Donaldson FPG10 specifications.
The FPG10 is a two-stage intake filtration system. Air first passes through an integrated tangential pre-cleaner: the airflow enters tangentially at high speed, and centrifugal force drives coarse particles to the housing wall. Approximately 85% of coarse dust is separated before reaching the primary element and is discharged automatically through the Vacuator dust valve at the base of the housing. Pre-cleaned air then enters the primary element, where cellulose filter media performs fine filtration. This architecture delivers the greatest benefit in dusty environments: the primary element carries only fine-particle load, maintaining longer service life under high-dust conditions.
The sealing method also differs from conventional air filters. FPG uses Donaldson's RadialSeal technology: a one-piece molded polyurethane end cap forms a radial seal directly against the housing outlet tube, eliminating the adhesive gasket found on older axial elements. Fewer parts means fewer failure points — gasket aging, detachment, and misalignment are eliminated in the FPG design, and no tools are required for installation or removal.

Technical Specifications
Filtration Performance
| Parameter | Value / Note |
|---|---|
| Filtration Rating | 5 μm (primary element) |
| Filtration Efficiency | 99.9% (per ISO 5011) |
| Pre-Cleaner Efficiency | Up to 85% coarse dust removal (tangential pre-cleaner stage) |
| Filter Class | Two-stage: centrifugal pre-cleaning + cellulose primary element; EN 779 HVAC classification does not apply |
| Dust Holding Capacity | Approx. 1,200 g |
Practical difference of the two-stage design: In a single-stage filter, the media must handle both coarse and fine particles. Coarse dust accumulates rapidly on the media surface, causing rapid pressure drop rise and short service life. By transferring the coarse-dust burden to the centrifugal pre-cleaner, the FPG10 improves the primary element's load profile — a key reason it is widely adopted on construction machinery and generator sets operating in dusty conditions.
Flow and Pressure Drop
| Parameter | Value / Note |
|---|---|
| Rated Airflow | ≤346 cfm / 9.8 m³/min (filter assembly rating) |
| Media Face Velocity | Approx. 0.038 m/s |
| Initial Pressure Drop | Approx. 0.5–1.0 kPa (50–100 mmH₂O) |
| Operating Differential Range | From new-element initial resistance to clogging alarm threshold |
| Alarm / Final Resistance | Per the unit's restriction indicator (yellow/red zone) |
| Pressure Drop vs. Energy | Each 1 kPa increase in intake resistance raises unit energy consumption by approx. 1% |
Pressure drop and energy consumption: Rising intake resistance reduces intake pressure and density. To maintain set discharge pressure and flow, the compressor must do more work, increasing specific power. Based on a theoretical compression ratio calculation at 0.7 MPa discharge pressure and 101.3 kPa atmospheric pressure:
| Intake Resistance | Compression Ratio | Relative Energy Increase |
|---|---|---|
| 0 kPa (new element) | 7.91 | Baseline |
| 2 kPa | 8.07 | +2.0% |
| 4 kPa | 8.24 | +4.1% |
| 6 kPa | 8.41 | +6.3% |
Engineering implication: As a filter goes from new to heavily clogged (0 → 6 kPa), unit energy consumption rises by approximately 6%. The cumulative electricity cost typically far exceeds the price of a filter element — which is why the original FPG10 housing includes a restriction indicator port: change intervals should be based on actual resistance, not calendar estimates.
Dimensions and Installation
| Parameter | Value / Note |
|---|---|
| Dimensions | 208 mm OD x 106 mm ID x 409 mm length |
| Construction | Pleated cylindrical element, two-stage RadialSeal primary |
| Effective Filtration Area | Approx. 4.3 m² |
| Pleat Count | Approx. 103 |
| Pleat Spacing | Approx. 4.8 mm |
| Mounting Interface | Radial push-in; end cap seals against housing outlet tube |
| Sealing | RadialSeal — one-piece molded polyurethane end cap forms radial seal, no separate gasket |
| Companion Element | Safety element (inner, backup protection) |
Procurement note: When cross-referencing replacements, verify all three dimensions: 208 mm OD, 106 mm ID, 409 mm length. The FPG design uses radial sealing; push the element in until the end cap contacts the outlet tube — no additional gasket is needed. Do not attempt to add a gasket; it will compromise the radial seal fit.
Material Composition
| Parameter | Value / Note |
|---|---|
| Media | Cellulose filter paper, per FPG10 specification |
| Media Weight | Approx. 130 g/m² |
| Inner/Outer Support | Galvanized steel perforated cage (inner) + outer mesh |
| End Cap | One-piece molded polyurethane (PU) end cap, encapsulating media ends and sealing surface |
| Seal | RadialSeal formed by the PU end cap body; no separate O-ring or gasket |
| Bonding | Molded integrally with end cap; no additional adhesive layer |
Structural note: A conventional axial element consists of a metal end cap, adhesive gasket, and separate seal ring — any one of which can age and cause bypass. The FPG design encapsulates the end cap, sealing surface, and media ends in a single polyurethane body, reducing part count and improving seal reliability. This is also what enables tool-free installation and removal.

Standard Maintenance and Installation Steps
A key feature of the FPG design is tool-free maintenance, with each service taking approximately 15 minutes.
Shut down, confirm zero pressure, lock out/tag out
Stop the unit, disconnect main power, and apply lockout/tagout. Criterion: controller shows system pressure at 0.Open the FPG filter service cover
Release the cover latches — the FPG design uses two spring latches or a twist-off cover, no tools required. Criterion: latches intact, cover not deformed.Remove the old element
Grip the polyurethane end cap and pull straight out. Criterion: note that the RadialSeal design has no gasket to peel off — if you find a residual gasket on the housing outlet tube, a non-genuine part was previously installed and must be cleaned off.Inspect the Vacuator dust valve
Check the Vacuator valve (rubber duckbill) at the base of the housing. Criterion: valve opens and closes freely, no caked dust, no obstruction. This is the most commonly skipped step in FPG maintenance and the most consequential — a blocked dust valve disables the pre-cleaner, transferring the full dust load to the primary element and significantly shortening its life.Inspect the pre-cleaner stage and housing for dust traces
Check for dust bypass tracks inside the housing and abnormal accumulation in the pre-cleaner swirl zone. Criterion: no dust tracks on the inner wall; if tracks are present, inspect the sealing surfaces.Install the new element
Push the 49164395 into the housing until the polyurethane end cap contacts the outlet tube. Criterion: end cap seats fully against the outlet tube; no gasket is needed or permitted.Reinstall the service cover and check the restriction indicator
Replace the cover and secure the latches. Confirm the restriction indicator is in the green zone; if resettable, press to reset and verify it returns properly. Criterion: green zone reading, indicator functions correctly.Start up and record
Start the unit, run to operating temperature, and read intake resistance. Criterion: resistance within the new-element baseline range; record date, operating hours, and resistance reading.
Installation rule: Do not start the unit before the element is seated. If the RadialSeal is not fully pushed into position, air will bypass directly through the gap between the end cap and outlet tube, rendering both the pre-cleaner and primary element ineffective — equivalent to running with no filter at all.
Frequently Asked Questions
What specification is the 49164395?
A two-stage RadialSeal primary element manufactured to Donaldson FPG10 specifications. The integrated tangential pre-cleaner removes approximately 85% of coarse dust before the primary element performs fine filtration.
Is it interchangeable with 49101637?
No. 49101637 is FPG09, with different dimensions and rated airflow. To confirm: read the specification marking on the end cap of the currently installed element — if it reads FPG10, order this part; if it reads FPG09, order 49101637.
Why does this element have no gasket?
Because it uses RadialSeal radial sealing. The polyurethane end cap body forms the seal directly against the housing outlet tube, eliminating the need for an adhesive gasket or separate seal ring. Fewer parts, fewer failure points, and less chance of incorrect installation.
What does the Vacuator dust valve do?
It is the dust discharge port for the pre-cleaner stage. Coarse dust separated by centrifugal force in the pre-cleaner falls by gravity to the base of the housing and is automatically discharged through the Vacuator valve. Once the valve is blocked, the pre-cleaner is completely ineffective, and all dust is forced onto the primary element. Inspect it at every filter change — this is the critical maintenance action for the FPG design.
How often should it be replaced?
The recommended interval is 2,000 hours or 3 months, whichever comes first. More accurately, monitor the restriction indicator: schedule replacement when resistance enters the yellow zone. In high-dust environments, replace earlier based on indicator readings.
Can the element be blown clean and reused?
No. This is a dry, disposable element — it cannot be washed or reverse-blown with compressed air. Reverse blowing damages the media fiber structure and creates invisible channels that allow unfiltered air to pass, which is more dangerous than not changing the filter at all.
Can a gasket be added to improve sealing?
No, and it is not necessary. RadialSeal relies on radial compression of the end cap body to form the seal. Adding a gasket pushes the element away from the outlet tube, compromising the seal fit and causing bypass.
The restriction indicator never moves — is that normal?
No. A stuck indicator is a common failure point that can give a "clean" reading even when the element is actually clogged. Press-check it at every service to confirm it returns properly; if it has failed, replace the element on a conservative time-based schedule until repaired.
How does the FPG plastic housing compare to metal housings?
The FPG injection-molded housing is corrosion-resistant, lightweight, and vibration-resistant — it will not rust in coastal salt-spray or humid environments. The tool-free design also speeds up field maintenance. This is a key reason the FPG series is widely used on construction machinery and mobile equipment.
How can I be 100% sure this is the right part?
Three steps: (1) Read the specification marking on the end cap of the currently installed element and confirm it is FPG10; (2) Measure the old element's OD and length to verify 208 mm and 409 mm; (3) If the old element has been discarded, provide the model marking on the filter housing, and we will cross-reference by FPG specification.
Compatible Equipment
This part is supplied to Donaldson FPG10 specifications and is suitable for Ingersoll Rand rotary screw air compressors equipped with an FPG10 air filter housing.
FPG10 is a Donaldson finished filter assembly specification, adopted by OEMs as a standard intake filtration unit. Key identification points:
| Identification Item | Specification |
|---|---|
| Filter Housing Specification | Donaldson FPG10 (elements interchangeable with FRG10 series) |
| Filter Housing Rated Airflow | ≤346 cfm / 9.8 m³/min |
| Role in Assembly | Primary Element |
| Other Specification in Series | FPG09 — corresponds to part number 49101637, different dimensions and airflow, not interchangeable |
| Sealing System | RadialSeal (polyurethane end cap radial seal) |
How to confirm compatibility
- Preferred: Read the specification marking on the end cap of the currently installed element. If it reads FPG10, this part applies; if it reads FPG09, order 49101637.
- Alternative: Measure the old element's OD and length to verify 208 mm x 409 mm.
- Fallback: Provide the model marking on the filter housing or a photo of the unit nameplate, and we will cross-reference by FPG specification.
Note on model coverage
Donaldson FPG10 is a universal filter housing adopted by multiple OEMs, so the compatibility range of this part is not limited to a specific list of machine models. The determining factor is whether the filter housing specification is FPG10, not the machine model itself. If the unit nameplate does not indicate the filter housing specification, confirm using any of the three methods above.
Related Components
The FPG10 filter housing is a complete system with 7 additional components serviced alongside the primary element. Listed by component — function — inspection point:
| Component | Function | Inspection Point |
|---|---|---|
| Safety Element | Backup element inside the primary, protecting downstream during primary damage or change intervals | Typically replaced on the same or every other cycle; check media for damage |
| Vacuator Dust Valve | Automatic dust discharge port for the pre-cleaner, expelling centrifugally separated coarse dust | Must check at every filter change: valve must open/close freely, no caked dust, no obstruction |
| Restriction Indicator | Indicates element clogging level; authoritative basis for replacement timing | Check needle returns properly; connecting line must be clear |
| Service Cover and Latches | Tool-free opening structure of the FPG housing | Check latches for cracks, cover for deformation; no air leaks when secured |
| FPG Housing Assembly | Injection-molded plastic housing with tangential inlet and pre-cleaner swirl zone | Check inner wall for dust bypass tracks; check plastic for cracks |
| Intake Hose and Clamps | Connects filter housing to engine intake | Check for cracks, aging, looseness — bypass leakage is as harmful as no filter |
| Other Series Primary Element | FPG09 — part number 49101637 | Different dimensions and airflow, not interchangeable; distinguish when stocking |
Companion replacement recommendation: The maintenance value of the FPG10 system centers on whether the pre-cleaner stage is working properly. When changing the primary element, inspect the Vacuator valve and restriction indicator at the same time. If either fails, primary element life is significantly shortened — their cost is far lower than the primary element, yet they determine how long it lasts.
