Rating
Ultimate
Recommended when highest filtration efficiency and dust loading capacity is needed.
Excellent
Excellent filter life, good filtration efficiency, very good operating performance for environment
Good
Performance and filter life above minimum criteria. A good upgrade in life cycle. Provides value over sufficient.
Sufficient
Acceptable filter life and filtration efficiency. When cost is the primary criteria, meets minimum performance requirements
5 Factors to consider when choosing a media Selecting the Right Media Pressure Drop Dust Holding
MERV
The initial efficiency of a filter
DUST HOLDING
How much dust the filter holds while maintaining air
PRESSURE DROP
Resistance to airflow over the life of a filter
ENVIRONMENTAL CONDITIONS
The ambient air conditions that affect the filter
OTHER PROPERTIES
Enhancements to aid efficiency, durability, corrosion resistance and filter life

TurboWeb
100% Synthetic spun bond media excellent moisture resistance, particulate release and high strength Dimensional stability provides consistent performance High Flow Media 41 Perm*
SX
Synthetic paper with low cellulose content, non-phenolic resin Strongest, most moisture resistant paper, high wet strength and permeability Medium Flow Media 25 Perm*
CX
Blended cellulose with synthetic fibers Proprietary grade with excellent efficiency High Flow Media 25 Perm*
QX
Blended cellulose and synthetic fiber paper, non-phenolic resin Utilizes proprietary resin system for improved structural strength and durability Medium Flow Media 16 Perm*
*Frazier Permeability in CFM, the higher the number the better
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 ASHRAE 52.2 - Current standard which provides relative initial efficiency of a filter. Good for evaluating initial efficiency but does not provide an indication of life expectancy. Consider ALL 5 FACTORS when choosing the right media. Even when a media has a higher MERV value, it may not be the best choice when considering the entire life cycle of a filter including initial cost.
Filters for Gas Turbines
Filters for Gas Turbines Prefilters, Panel Filters, Lube Oil/Hydraulic Filters and Service: We do it all! One vendor. One purchase order. One company. Mini V Bank Filters
Prefilters V-shaped minipleat modules are fully sealed to avoid any possible bypass of dust particles. The extensive media surface creates a very low resistance to airflow saving energy costs and increasing flter life.
Our prefilters protect the high-efficiency element by forming a barrier to capture large particles, air-born fibers and unburned hydrocarbons. Our wraps are an inexpensive way to protect against seasonal challenges such as air born seeds and insects. The result, a longer filter life for the cartridge. Due to the generously porous pre filter, the impact on system pressure drop is minimal.
V Pack and Pulse Panel The sturdy construction, galvanized steel frame and moisture resistant media will help these V Pack and Pulse Panel filters last. Each filter comes with a material and workmanship warranty. Highest quality media means best filter performance.
Whether your collector needs routine or preventive maintenance services, Midwesco Filter has an experienced and HAZWOPER professionally trained crew 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 or renovation projects can be performed by our Turnkey Management Team.
