Product Overview
The Ingersoll Rand 47667846001 47638843001 Air Filter Safety Filter is a secondary air filtration component used in compatible Ingersoll Rand compressor intake systems. It works behind the primary air filter to provide an additional filtration stage for the incoming air path.
In a compressor intake assembly, the primary filter removes most airborne contamination before air reaches the compressor. The safety filter provides additional protection within the filter housing, helping limit the amount of particulate contamination that can enter the compressor if the primary filter is disturbed, damaged, or removed during servicing.
The 47638843001 safety filter is particularly relevant during compressor maintenance because the intake system may be exposed to contamination whenever the primary filter is removed. Keeping the secondary filter correctly installed helps maintain an additional barrier between the external environment and the compressor air-end.
As a safety filtration component, this filter does not replace the primary air filter or perform compressor control functions. Its purpose is to provide secondary protection within the designated intake filtration arrangement.

Product Features
- Safety filter for compatible Ingersoll Rand compressor intake systems
- Provides a secondary filtration stage behind the main air filter
- Helps limit particulate entry into the compressor air-end
- Supports additional intake protection during primary filter servicing
- Suitable for scheduled compressor maintenance
- Works as part of a multi-stage intake filtration arrangement
- Helps maintain cleaner air conditions downstream of the intake filter housing
- Suitable for replacement of a used or contaminated safety filter
Working Principle
The 47638843001 safety filter is installed downstream of the primary intake filter within the designated air filter housing. Under normal operation, incoming air first passes through the main filter and then through the safety filter before reaching the compressor intake.
Ambient Air → Main Air Filter → 47638843001 Safety Filter → Compressor Intake → Air-End
The safety filter acts as a secondary barrier against particulate contamination. Its role becomes particularly important if the primary filter is removed during maintenance or if the primary filtration stage is compromised.
The safety filter itself does not regulate airflow or control compressor operation. Its contribution is physical filtration within the intake path. The condition of both filtration stages, together with the filter housing and sealing surfaces, determines the effectiveness of the overall intake protection system.
Role in an Ingersoll Rand Compressor Air Intake Architecture
The 47638843001 occupies the secondary filtration layer of the compressor intake system. It works with the main air filter and filter housing to protect the compressor air-end from airborne contaminants.
Ambient Air → Main Air Filter → 47638843001 Safety Filter → Intake Ducting → Compressor Air-End → Compressed-Air System
| System Element | Function |
|---|---|
| Ambient Air | Provides incoming air to the compressor |
| Main Air Filter | Performs primary removal of airborne contamination |
| 47638843001 Safety Filter | Provides secondary intake-air filtration |
| Filter Housing | Contains and supports the filtration elements |
| Intake Ducting | Transfers filtered air toward the compressor |
| Compressor Air-End | Compresses the incoming air |
| Compressor Controller | Monitors and controls compressor operating functions |
The safety filter is therefore part of the physical air-protection system upstream of the air-end. It complements the primary filter rather than replacing it.
Industrial Applications
| Application | Typical Use |
|---|---|
| Screw Compressor Maintenance | Replacement of secondary intake safety filters |
| Industrial Air Compression | Additional filtration of compressor intake air |
| Manufacturing Plants | Secondary protection against airborne contamination |
| Process Industries | Maintaining intake-air cleanliness in compressor systems |
| Plant Utility Systems | Maintenance of multi-stage compressor intake filtration |
| Preventive Maintenance | Scheduled inspection and replacement of safety filters |
| Compressor Overhaul | Renewal of secondary intake filtration components |
Installation and Maintenance
- Confirm that 47638843001 is the correct safety filter for the compressor being serviced.
- Shut down and isolate the compressor before opening the intake filter housing.
- Allow the intake system to reach a safe maintenance condition before removing filtration components.
- Clean the area around the filter housing to prevent loose contamination from entering the intake system.
- Inspect the existing safety filter for dust loading, deformation, moisture, or physical damage.
- Check the main filter and safety-filter housing at the same time for contamination or deterioration.
- Inspect the sealing surfaces before installing the replacement safety filter.
- Install the safety filter in the correct position and ensure it seats properly.
- Verify that the filter housing is correctly closed and that no obvious bypass path remains.
- Inspect intake ducting and connections for damage or loose joints before restarting the compressor.
- Start the compressor under controlled conditions and monitor relevant intake and operating indications.
- Record the safety-filter replacement and any unusual contamination findings in the compressor maintenance history.

Technical FAQs
What is the purpose of the 47638843001 safety filter?
The safety filter provides a secondary filtration stage in the compressor intake system. It offers additional protection against particulate contamination downstream of the main air filter.
Can the 47638843001 replace the main air filter?
No. The safety filter and main air filter serve different positions within the intake filtration arrangement. The safety filter is intended to provide secondary protection and should not be treated as a substitute for the primary filter.
Why should the safety filter be inspected when replacing the main air filter?
Removing the main filter can expose the intake housing to dust and other contamination. Inspecting the safety filter at the same time helps identify accumulated contamination, physical damage, or sealing problems that could affect downstream air cleanliness.
What should be checked if compressor intake restriction increases after replacing the filters?
Check that both filter elements are correctly positioned, the housing is properly closed, and the intake ducting is unobstructed. The main filter, safety filter, housing seals, and upstream intake path should all be considered when investigating abnormal restriction.
