ASHRAE 52.2 - Current standard which provides relative initial efficiency of a filter.


Independent Testing Terms and Meaning

ASHRAE - American Society of Heating Refrigeration and Air Conditioning Engineers

ASHRAE 52.1 - Obsolete standard, replaced with 52.2 standard

Good forevaluating initial efficiency but does not provide an indication of life expectancy.

Consider ALL 5 FACTORSwhen choosing the right media.

Even when a media has a higher MERV value, it may not be the best choice whenconsidering the entire life cycle of a filter including initial cost.

Prefilters, Panel Filters, Lube Oil/Hydraulic Filters and Service:

We do it all! One vendor. One purchase order. One company.

Whether your collector needs routine or preventive maintenance services,Midwesco Filter has an experienced and HAZWOPER professionally trainedcrew available. Midwesco Filter has been servicing baghouses and cartridge

dust collectors for more than twenty years.

Our OSHA and EMR ratings meet or exceed industry standards. Rebuild orrenovation projects can be performed by our Turnkey Management Team.

Our prefilters protect the high-efficiency

element by forming a barrier to capturearge particles, air-born fibers and un-

burned hydrocarbons. Our wraps are annexpensive way to protect against season-al challenges such as air born seeds and

nsects. The result, a longer filter life for thecartridge. Due to the generously porous

pre filter, the impact on system pressuredrop is minimal.

The sturdy construction, galvanizedsteel frame and moisture resistant m

will help these V Pack and Pulse Panfilters last. Each filter comes with a

material and workmanship warranty

Highest quality media meanbest filter performance.

Prefilters

V Pack and Pulse Panel


V-shaped minipleat modules are fully

sealed to avoid any possible by-pass of dust particles. The extensive

media surface creates a very lowresistance to airflow saving energy

costs and increasing flter life.
