Schneider Electric (Barber Colman) FILN05 Air Filter

The Schneider Electric (Barber Colman) FILN05 is a high-performance inline pneumatic air filter engineered for point-of-use protection in complex building automation systems (BAS) and HVAC operations. As a professional-grade K-335 replacement filter, this unit utilizes a high-efficiency HEPA Microflex filter tube permanently bonded within a durable, transparent nylon housing. Designed for precision filtration, it protects downstream actuators and control valves by removing particulate matter, moisture, and debris that compromise system calibration. The straight barb fittings are specifically sized for 1/4 inch O.D. poly tubing, ensuring a secure, leak-free friction fit without the need for additional clamps under standard operating pressures. With a maximum rating of 100 psi and 200°F, this disposable pneumatic filter provides a 1.4 scfm flow capacity at 1.5 psid, offering a cost-effective solution for preventing orifice clogging in sensitive pneumatic controls. Note that this component is not compatible with synthetic lubricants.

• Efficient Contaminant Removal: Utilizes HEPA Microflex technology to trap fine particulates, extending the service life of pneumatic actuators.
• Direct Retrofit Compatibility: Serves as the precise replacement for the Barber Colman K-335, allowing for immediate installation in existing control loops.
• Visual Maintenance Monitoring: The transparent nylon housing allows technicians to perform quick visual inspections for filter contamination.
• Simplified Installation: Integrated straight plastic barbs facilitate rapid connection to standard 1/4" O.D. poly tubing used in HVAC controls.

Is the FILN05 compatible with all pneumatic systems?
This filter is designed for standard air lines but should not be used in systems utilizing synthetic lubricants, as they may degrade the nylon housing.

What is the maximum pressure rating for this inline filter?
The FILN05 is rated for a maximum pressure of 100 psi at 100°F, making it ideal for most low-pressure HVAC control circuits.

How often should a pneumatic air filter be replaced?
The filter should be replaced as soon as visual inspection reveals significant discoloration or when a noticeable pressure drop occurs across the unit.
