The TT-4-CV Fuel Tank Breather Filter Element is made of 100% silicone filter material, which can effectively filter water vapor and other impurities in the fuel tank. The filtration accuracy can reach up to 1 micron. Usually installed on the ventilation hole of the gearbox oil tank.

Why install a TT-4-CV fuel tank respirator? Because the liquid level of the oil tank fluctuates up and down during the use of the hydraulic station, in order to maintain the same atmospheric pressure between the oil tank and the outside, a channel must be established between the oil tank and the atmosphere. Installing a respirator on this channel can filter out some small particles and moisture when air enters and exits the oil tank. If the oil tank is only equipped with a channel without a respirator, the oil will be contaminated. If a channel (oil tank opening) is not installed, the oil tank will change with the change of the liquid level, and the pressure will also change, which will affect the operation of the hydraulic station.
