Tank Supply Company has created the highest quality air sterilizer on the market today, the PAS, PAS provides maximum air quality to your liquid sweetener tank by using state of the art filtration. This filtration system creates a completely sterile environment. Today most units utilize air filters that restrict the movement of air out of the tank. These units are moisture collectors that breed unwanted organisms. The vent system is a curved, U-shaped vent that is insulated and protected from the elements. Tank Supply knows this design will offer you the best venting system on the market and at the lowest cost to you."

• Ultraviolet Lamps are internally enclosed in Quartz Sleeves
• The Pre-Filter is six times larger then the standard 10x10x1 Electrostatic Filter
• Blower motor contaminates are filtered prior to the sterile chamber. Blower motor contaminates must be filtered out
• Air is pushed through the HEPA filter. Air is filtered down to .03 microns.
• Air flow is temperature controlled. Hot air only into the tank will decrease moisture and potential for microorganisms and mold growth.
• Unique stainless vent system with less restrictive airflow and less likely to become a point of inoculation.
• Internal wiring is not exposed to direct ultraviolet light.

This blower system was designed for large (20,000 gallon+) liquid storage tanks. The HAV utilizes the same patented technology as the PAS System, but does not incorporate ultraviolet light. It operates on the principal of eliminating the dew point within the head space of the tank, not allowing yeast, mold or any other inoculates to take hold.

The HAV blower forces air through a specially designed HEPA Filter, filtering air to .3 microns, and entering the tank at a volume of 600 CFM. This air circulates through the headspace and exits through a specialty vent that does not restrict the exit air flow. Unlike other systems that pull air through the filters and actually have considerable filter bypass air entering the tank; it is virtually eliminated by this system. Due to the nature of the filters and design, new gasket material is in place every time you change out the filters. This maintains a very tight seal around all the components to eliminate air bypass.

The Pre-Filter is made of 100% Dacron fibers, 4 ply thick with a built in tacifier. This Pre-Filter will trap particulates down to 10 microns, much smaller then most electrostatic filters, taking the boulders out of the air and reducing the build up load on the HEPA. This Pre-Filter is over 1500 sq. inches, much larger then competitor filters and far more efficient.

With the design of this system, all blower contaminants are trapped in the HEPA. All blower motors are dirty components of any system and throw off particulates from the windings, bearings and armatures that can become part of your ingredient if not treated properly within the system. The HAV will not allow anything but the cleanest, purest air possible to enter the tank headspace.

Normal filter change out is once a year, although changing out the Pre-Filter more frequently can extend the HEPA filter life. Made up of all stainless steel construction, this HAV system will provide many years of service.
