LargeFeatures:
K-PAK S Series filter contains moisture-resistant pleat stabilizers on both sides of the media pack. This ensures that the tapered pleat configuration will not be deformed throughout the service life of the filter. The design of the pleat stabilizer offers maximum media filtration area and dust holding capacity, furthermore extending filter life span.
Efficiency:
Per ASHRAE 52.1-1992 standard (equal to EN779), the filters have an average atmospheric dust spot efficiency range 45-50%, 60-65%, 80-85% and 90-95% (in NBS Test Method); per ASHRAE 52.2, the efficiency is MERV9, MERV11, MERV12 & MERV14.
Media:
W-PAK S-Series filters are manufactured of Multiple Layers Synthetic Microfiber formed into a pleated configuration. The Synthetic Microfiber builds up in non-woven layers to strengthen Multi-layers and eliminate fiber shedding.
It contains non-glass fiber (to be thought a healthy hazard). W-PAK S-Series filters are not affected by extreme moisture and humidity conditions, unlike wet glass fibers that will be lost up to 20% efficiency. The media is color coded by efficiency.
Media Support Grid:
A corrosion-resistant metal support grid is bonded to the media to strengthen pleat construction and stability.
frame:
The enclosing frame is a galvanized steel construction. Diagonal supports on both upstream and downstream sides enhance the construction of the filter. This construction provides W-PAK filter with exceptional strength and durability for a longer life span. It is available in header or non-header type.
