Critical Air and Venting for Dairy Production

High-Quality Dairy Utilities

Uncontrolled contamination in dairy manufacturing takes its toll in many ways. With the many sources of contamination present in dairy plants, risk is high for product recall and its profit-reducing consequences of lost sales, lost product and lost brand equity. 

Air Sanitation

Air or gas used for product agitation or transportation, drying of products or working surfaces and incorporation into dairy product must be sanitary. The 3A standard for supplying air under pressure in contact with milk, milk product and product contact surface is Number 604-03. However, the use of “3A Standard Air” produces a visually clarified fluid to the naked eye, but does not assure safe microbial quality.

Profile® Star Filters
Profile Star filter cartridge The Profile Star filter cartridge combines the advantages of a continuously graded pore structure and a unique pleated geometry to provide an increase in effective filtration area and service life.


ZM Coalescer 
ZM coalescing filters are specifically designed for critical applications where high efficiency of aerosol removal is required.  Located downstream of liquid/gas contacting devices and upstream of cartridge filters, ZM Coalescers collect liquid aerosols and coalesce them into larger droplets which drain by gravity into the sump of the filter housing
