Filler Breather with Check Valve

Threaded filler breathers: manufactured from thermoplastic material (Polyamide 66), max operating temperature 100°C (212 F). TSV - TSAV models are as standard produced in black with a red lid, complete with encased hydraulic symbol for check valve. For large quantities a company logo can be encased beside the symbol.

• Standard seal: flat rubber seal, 70 shore.
• The model TSAV with plated steel dipstick, is as standard produced in length 195mm measured from the point making contact with the surface of the tank to the bottom of the dipstick.
• The filler breathers TSV - TSAV are similar to the models TMDV and TMDAV but have smaller space requirements. They are used in applications where a pressure needs to be maintained with the tank.
• The check valve will open when a pressure is reached of approx. .20 - .25 bar (3 - 3.6 PSI) and will close reset at similar pressure. The check valve will allow air to vent out under the above conditions, but does not allow air to move back in, thus preventing dust particles or other forms of contamination form the atmosphere to enter the oil. Extensively used in small oil tanks, gearboxes, gear reducers, torque multiplies and transmissions.
• The model TSAF has all the characteristics of “TSAV” but is fitted with a polyurethane air filter instead of the check valve.
