Dwyer 2230 Air Filter Kit 80 Psi 1/8 Inch Npt

Product Description

The DWYER 2230 is an air filter kit designed to clean and condition compressed air in pneumatic control systems and instrumentation lines. It accepts 1/8 inch NPT threaded connections and is rated for a maximum operating pressure of 80 psi with a measurement accuracy of 2 percent. Weighing approximately 1.17 pounds, the unit is compact enough for tight instrument panels and utility enclosures. Licensed HVAC technicians and instrumentation technicians install this type of filter to remove particulates and moisture from air supply lines, protecting downstream gauges, controllers, and pneumatic actuators from contamination damage.

The DWYER 2230 is suited for residential and light commercial HVAC control systems, pneumatic instrumentation setups, and compressed air distribution points where clean, dry air is required at the point of use. It is a practical fit for instrument air supply drops, pneumatic thermostat lines, and similar low-flow compressed air applications. The 1/8 inch NPT thread size makes it compatible with standard instrumentation fittings commonly found in these systems.

Key Features

• Maximum operating pressure of 80 psi for compressed air service
• 2 percent accuracy rating for reliable air quality performance
• 1/8 inch NPT threaded connection for standard instrumentation fittings
• Compact, lightweight design at approximately 1.17 pounds
• Suitable for pneumatic controls, instrumentation air lines, and HVAC auxiliary air systems

Compatibility

Designed as an OEM-style replacement or direct-install air filter kit for pneumatic instrumentation and compressed air supply systems using 1/8 inch NPT threaded connections rated up to 80 psi.

Installation Notes

Installation should be performed by a qualified HVAC technician or instrumentation professional familiar with compressed air systems. Depressurize and isolate the air supply line completely before removing any existing filter or fitting. Use appropriate thread sealant on NPT connections and do not overtighten fittings, as this can crack the filter body. Verify system pressure does not exceed the 80 psi rating after restoring air supply.
