TST-01 Oil Strainer

The TST-01 serviceable in-line oil strainer from Westermeyer is designed for use on CO2 systems at transcritical pressures. These units feature an integrated sight glass and are constructed of carbon steel with a nickel-plated finish.

When dealing with transcritical pressures, shielding the compressor from debris is as crucial as ever. This is why Westermeyer Industries has developed the TST-01 Oil Strainer series — as the final line of defense to monitor the oil path and screen out any contaminants. These units are constructed from carbon steel and are designed for use with CO2 at transcritical pressures, with a maximum working pressure of 2031 PSI.

The Westermeyer TST-01 Oil Strainer is fully serviceable, with a removable mesh strainer basket for easy cleanup and removal of debris. Other features include an integrated sight glass and full nickel plating for long-lasting corrosion resistance. These units are UL listed and available with either NPT or ODS connections. Contact Westermeyer Industries for more information.
