Replaces Bullard 41AF Flanged Breathing Air Filter Cartridge – 41 Series, RPB APF3100

Replaces Bullard 41AF Flanged Breathing Air Filter Cartridge – 41 Series, RPB APF3100

Maintain clean, filtered compressed breathing air with this quality aftermarket flanged filter cartridge designed to replace Bullard 41AF in compatible 41 Series airline filtration systems.

This multi-layer filter cartridge is designed to reduce oil particulates, odors, and certain organic vapors from compressed air supplied to industrial breathing-air filtration equipment.

It also cross-references RPB Safety APF3100 and A-BEC Industries 232-2145, making it a useful service component for maintaining compatible abrasive blasting and supplied-air respirator filtration systems.

IMPORTANT: THIS FILTER DOES NOT REMOVE CARBON MONOXIDE AND CANNOT, BY ITSELF, PRODUCE OSHA GRADE D BREATHING AIR.

What the Filter Cartridge Does

The Bullard 41AF-style filter cartridge is used inside compatible compressed breathing-air filtration assemblies.

As compressed air passes through the cartridge, its multi-layer filtering system helps trap and reduce certain contaminants before the air continues downstream.

The cartridge is designed to reduce:

• Oil particulates

• Certain airborne particulate contaminants

• Odors

• Certain organic vapors

Maintaining the filter cartridge helps preserve the filtration system's intended performance.

The cartridge does not remove carbon monoxide, correct oxygen deficiencies, or make an unsuitable compressed-air source safe for breathing.

Designed for Bullard 41 Series Airline Filters

This flanged cartridge is designed as an aftermarket alternative to the Bullard 41AF filter cartridge used in compatible Bullard 41 Series filtration equipment.

The 41 Series is commonly used in industrial compressed-air filtration applications, including systems supplying breathing air to abrasive blasting respirators.

Because filter assemblies and cartridge configurations can vary, always verify the original filter cartridge part number and physical configuration before ordering.

When Should the Filter Be Replaced?

The recommended replacement interval is every 90 days, or sooner depending on incoming air quality and operating conditions.

More frequent replacement may be necessary when the compressed-air supply contains higher levels of oil, moisture, or other filterable contaminants.

A filter cartridge should also be replaced whenever its condition or service history indicates that continued use may compromise filtration performance.

Common Reasons for Replacement

• Cartridge has reached its recommended service interval

• Increased contamination in the compressed-air supply

• Oil or moisture contamination

• Noticeable deterioration in filtration performance

• Cartridge is damaged

• Filter assembly is undergoing scheduled maintenance

• Existing cartridge has an unknown service history

• Restoring an older breathing-air filtration system

Why Routine Filter Replacement Matters

A compressed breathing-air filtration system requires regular maintenance to perform as intended.

As the cartridge collects contaminants, its filtration capacity can become reduced. Neglecting filter replacement may allow filterable contaminants to pass downstream or contribute to reduced system performance.

Replacing the cartridge at the recommended interval is an important part of maintaining the filtration assembly.

A new filter cartridge does not eliminate the need for air-quality testing, proper compressor maintenance, or carbon monoxide monitoring where required.

Carbon Monoxide Warning

THIS FILTER DOES NOT REMOVE CARBON MONOXIDE.

Carbon monoxide is a colorless, odorless, potentially deadly gas that can contaminate compressed breathing air.

A compatible carbon monoxide monitoring system may be required as part of the overall breathing-air installation.

Carbon monoxide monitors detect elevated CO concentrations but do not remove carbon monoxide from the air supply.

OSHA Grade D Breathing-Air Requirements

FILTRATION ALONE CANNOT PRODUCE OSHA GRADE D BREATHING AIR FROM AN UNSUITABLE COMPRESSED-AIR SOURCE.

Breathing-air requirements address several characteristics, including:

• Oxygen content

• Carbon monoxide concentration

• Carbon dioxide concentration

• Condensed hydrocarbon content

• Odor

The compressed-air source must meet all applicable breathing-air quality requirements independently of the filter cartridge.

This cartridge must be used only as part of an appropriately designed, verified, and maintained breathing-air filtration system.

Applications

• Bullard 41 Series airline filtration systems

• Compatible industrial breathing-air filters

• Supplied-air abrasive blasting respirator systems

• Sandblasting and shot blasting operations

• Industrial painting and coating facilities

• Structural steel surface preparation

• Shipyard and marine maintenance

• Industrial compressed-air filtration applications

This is an aftermarket component and is not manufactured by Bullard, RPB Safety, or A-BEC Industries.

The filter housing, regulator, pressure gauge, breathing-air hoses, respirators, and other components are sold separately unless specifically stated otherwise.

Always verify the original part number, cartridge dimensions, flange configuration, and filtration-system compatibility before ordering.

Breathing-Air Safety

Use this cartridge only in filtration systems for which its compatibility and suitability have been established.

When the filtration system supplies breathing air, follow the equipment manufacturer's requirements and applicable respiratory protection regulations, including OSHA 29 CFR 1910.134.

The compressed-air source must provide breathing-quality air, and the complete system must be maintained and monitored according to applicable requirements.
