Kits-for-Air-Filter-Gage-Switch

Supported Applications

The Dwyer Kits for Air Filter Gage Switch series provides accessory packages designed to connect pressure switches and differential pressure gages in air filter monitoring systems. These kits facilitate the installation of sensing lines required for evaluating airflow resistance across filters.

• Air filter switch installations without a separate gage
• Pressure switch setups used with Magnehelic® or Series 250 AF gages
• Configurations utilizing Mark II gages alongside pressure switches

Operating Conditions & Performance

The series consists of accessory components rather than active measurement instruments; therefore, performance specifications such as accuracy class, response time, or operating temperature ranges are not defined for the kits themselves. The accessories serve to establish physical connections between process points and instrumentation.

• Includes tubing lengths specified in inches (e.g., 5' lengths)
• Incorporates compression fittings sized at 1/8" NPT to 1/4" tubing

Configuration Options

The series offers three distinct accessory configurations tailored to specific gage types and installation requirements. Each kit includes the necessary hardware to complete a pneumatic circuit for air filter monitoring.

A-602: Air Filter Kit (Switch Only)

• Intended for using a switch without a gage
• Includes two pressure tips with integral compression fittings
• Contains two 5' lengths of 1/4" aluminum tubing
• Provides two 1/8" NPT to 1/4" tubing compression fittings

A-603: "T" Kit (Magnehelic® or Series 250 AF)

• Designed for use with Magnehelic® or Series 250 AF gages equipped air filter kits
• Includes two 1/8" NPT to 1/4" tubing compression fittings
• Provides two compression tees

A-604: "T" Kit (Mark II Gage)

• Designed for use with Mark II gages
• Includes two plastic tubing connector tees
• Contains two plastic tubing to 1/8" NPT adapters

Key Product Differences

Variants within the series differ by their intended instrumentation compatibility and included hardware materials. The A-602 model supports switch-only applications with aluminum tubing, while the A-603 and A-604 models provide "T" configurations for specific gage families using compression tees or plastic adapters respectively.

• A-605 is listed as an enabled variant in the series bundle but lacks a detailed description in the provided documentation
