Product Overview

The Purolator® Hi-E® 40 CB activated carbon pleated air filter is designed to promote indoor air quality through enhanced odor control by removing airborne molecular contaminants present at levels less than 1 ppm. The filters use non-woven dual-layer pleated filter media composed of synthetic fibers. The carbon-loaded media is highly rigid and self-supporting, with no external wire reinforcements. The pre-filter layer performs to MERV 8 per ASHRAE 52.2, providing users with a powerful combination of particulate and odor removal in a single package.
The filter is loaded with 200 grams per square meter of 60% active, 20x50 mesh-size carbon particles, which provide up to six times the adsorbent surface area of standard GAC carbon. This results in higher particle capture capacity and extended service life. Fine mesh carbon granules are bonded to the synthetic fibers by a unique thermal process that requires no adhesive and blinds less than 1.5% of each carbon particle’s effective surface area. As a result, more than 98.5% of the carbon surface is exposed to contaminated air, thus ensuring maximum gas adsorbing capacity.
The Hi-E® 40 CB filter elements are enclosed in a two-piece heavy-duty, moisture-resistant beverage board frame. When assembled, the fully bonded double-wall frame combines with the integral corner flaps and forms a rugged, durable filter which will not rack, warp or leak under normal operating conditions.
Common applications of the filter include air conditioning filters, furnace filters, heating vents, air intakes, air purification devices and ozone removal devices. Appropriate end users include (but are not limited to) hospital facilities, chemical plant offices/labs, pollution control areas, sewage disposal and waste management plant offices, airports, kitchens and restaurants.

Markets
• Commercial and Industrial HVAC
• Process Air Filtration

Applications
• Air intakes or purification systems in hospitals, chemical plants, laboratories, airports, waste management facilities, commercial kitchens, etc.
• Ozone removal devices


Benefits
• Small (20 x 50 mesh) carbon particles and pleated configuration maximize adsorbent surface area
• Low pressure drop: Uniform dispersion of carbon throughout media, not just on surface, lets air flow freely
• Longer filter life, minimal shedding/dusting: thermal bonding of media to carbon exposes maximum adsorbent surface area
• More adsorbent: pound for pound, the carbon media is six times more effective than competitive GAC carbons
• Performs to MERV 8 per ASHRAE 52.2 test standard, offering a powerful combination of particle capture and odor control
