Dwyer 2040 Air Filter Kit 15 Psi 1/8 Inch Npt

Product Description

The DWYER 2040 is a compressed air filter kit designed for low-pressure pneumatic instrumentation systems. It removes particulates and moisture from air supply lines to protect downstream gauges, transmitters, and control devices. The kit is rated for a maximum working pressure of 15 psi and carries a 2% accuracy specification. The 1/8 inch NPT thread connection suits standard instrument tubing fittings. With a maximum pressure equivalent to 40 inches water column and a maximum operating temperature of 140 degrees F, this filter kit fits cleanly into instrument air supply applications where clean, dry air is required for reliable operation.

This filter kit is used in light commercial and industrial pneumatic control systems where instrument-quality air must be supplied to gauges, controllers, or actuators. Typical installations include HVAC pneumatic control panels, compressed air distribution manifolds, and instrument air supply headers. HVAC controls technicians and instrumentation mechanics are the primary installers. The 1/8 inch NPT port size suits small-bore tubing connections common in low-pressure instrument air circuits.

Key Features

• 15 psi maximum working pressure suitable for instrument air supply systems
• 2% accuracy rating for dependable pressure management
• 1/8 inch NPT thread connection compatible with standard instrument fittings
• Rated to 140 degrees F maximum operating temperature
• 40 inch water column pressure range for low-pressure pneumatic applications

Compatibility

Designed as an OEM-style replacement or direct-install filter kit for low-pressure pneumatic instrument air supply lines using 1/8 inch NPT threaded connections.

Installation Notes

Installation should be performed by a qualified HVAC controls technician or instrumentation mechanic. De-pressurize and lock out the compressed air supply line before removing any existing filter or fitting. Use thread sealant rated for compressed air service on the NPT connections. Verify that system operating pressure does not exceed the 15 psi maximum rating of this kit before returning the system to service.
