The stainless steel sanitary respirator is a gas balancing device specially used in closed systems. It can automatically adjust the air in and out to maintain the pressure balance between the inside and outside when the pressure inside the tank or pipeline changes. It is equipped with a precision filter element inside to ensure that the incoming air is clean and sterile, and prevent microorganisms and particles from contaminating the fluid medium. Stainless steel sanitary respirators are usually installed on the top or vent position of sterile storage tanks, fermentation tanks, blending tanks, pure water tanks and conveying pipelines in industries such as food, pharmaceuticals, dairy products and chemicals. Common types of stainless steel sanitary respirators include the following: standard sanitary respirators, fire-retardant sanitary respirators, pressure-balanced sanitary respirators, and liquid-sealed sanitary respirators.

Stainless Steel Sanitary High Pressure Quick-install PTFE Respirator For Food
The core of the design of stainless steel sanitary respirators is to solve the problem of micro-pressure imbalance caused by liquid level fluctuations, temperature changes or changes in external environmental pressure during the dynamic operation of closed tanks or pipeline systems. It is not only a passive pressure regulating device, but also acts as an "intelligent barrier", using high-efficiency filters to prevent microorganisms, dust and pollutants in the external air from entering the tank, ensuring that the internal medium always remains sterile and pure. At the same time, it can also prevent structural damage caused by excessive pressure difference between the inside and outside of the tank, thereby maintaining the stability and safety of the equipment in a harsh sanitary production environment.
Working Principles
The working principle of the stainless steel sanitary respirator is based on the dual mechanism of pressure balance regulation and high-efficiency filtration. When the liquid level changes or the temperature fluctuates inside the closed tank or pipeline system, the internal pressure will increase or decrease. If the internal pressure is higher than the external pressure, the exhaust valve of the respirator will automatically open, and the excess gas will be discharged through the high-efficiency filter element to prevent the tank from deforming or leaking due to overpressure; if the internal pressure is lower than the external pressure, the atmosphere enters the respirator through the air inlet and passes through the precision filter to remove microorganisms, dust and other pollutants to ensure the cleanliness of the incoming gas, while replenishing the air pressure in the tank to prevent the formation of vacuum negative pressure.
The options for stainless steel sanitary respirators are as follows:
Filter material: PTFE, PP, glass fiber, stainless steel sintered mesh, etc., with different filtration precisions.
Interface mode: quick installation, welding, threaded, flange connection, suitable for different pipeline systems.
Breathing direction: one-way intake, one-way exhaust, two-way breathing, different ventilation modes can be selected.
Fire-blocking device: optional fire-blocking net, suitable for flammable media environment.
Sterilization method: supports online steam sterilization or chemical disinfection.
Pressure setting: different opening pressures can be selected to match different process requirements.
Surface treatment: mirror polishing, electrolytic polishing, sandblasting, to meet different hygiene standards.

Features
● The stainless steel sanitary respirator adopts a precisely calculated airflow channel and an automatic pressure compensation mechanism, which enables the respirator to respond quickly to pressure changes and avoid turbulence or secondary contamination of particles caused by sudden changes in airflow.
● The filter element of the stainless steel sanitary respirator adopts a nano-scale porous membrane structure, which can achieve high-efficiency filtration at extremely low pressure differences, reduce the impact on the internal pressure stability of the tank, and improve the sensitivity of the respirator.
● The stainless steel sanitary respirator adopts a special inner cavity design to prevent condensed water from accumulating on the surface of the filter element under low temperature conditions, avoiding the decrease in ventilation capacity or microbial growth caused by water blockage.
● The stainless steel sanitary respirator uses a two-way fluid path design to automatically perform forward and reverse airflow flushing when the tank air pressure fluctuates, reducing filter element blockage, increasing service life, and reducing maintenance frequency.
● The stainless steel sanitary respirator adopts laser welding and integral molding technology to avoid the micro-crack problem of traditional welding points, improve the hygiene level, prevent bacteria from hiding, and enhance the pressure resistance and sealing of the overall structure.
● The stainless steel sanitary respirator filter frame adopts a combination of polymer materials and stainless steel with matching thermal expansion coefficients, which can maintain a stable size structure in high and low temperature environments.
