Long-Life Box Air Filters
Multiple panels maximize filtering surface area for long service life. These MERV 14 air filters capture particles down to 0.3 microns. They have a V-shape design and a rigid frame that withstands fluctuations in airflow, such as those created by variable air volume systems. The more filter panels they have, the more filtering surface they have for a longer service life.
Actual size is up to 5/8" less than trade size.

HEPA Long-Life Box Air Filters
Extend the time between filter changes in laboratories, hospitals, and other places with a high risk of airborne contaminants. These filters have tight pleats, which increase the surface area for catching particles. They’re a HEPA filter, so they capture small particles, such as allergens and germs, more efficiently than standard air filters.
Filters with an aluminum frame have a V-shape design that increases the filtering area and reduces resistance to air, leading to an even longer life than filters with a standard design.

High-Efficiency Long-Life Panel Air Filters
With tight pleats, these filters have a larger surface area than filters with standard pleats for improved efficiency and an even longer life. These filters strike a good balance of filtering efficiently while allowing airflow, making them a more cost-effective option than higher rated filters. All are effective at capturing common allergens such as dander, mold spores, and pollen. Use them in data centers and other locations that require extra-clean air.

Inline Air-Release Valves for Water
- Max. Pressure: 125 psi
- Temperature Range: 40° to 240° F
Eliminate air pockets without stopping flow—these valves have an internal wire brush that traps air bubbles and discharges them through the top relief port while allowing inline flow from the inlet to the outlet. They are often used to increase efficiency in heating and cooling systems. The vented relief port exhausts discharge directly. Valves have a durable bronze body for a long service life.
