The Parker DP® HT High-Temperature Pleated Air Filter is engineered for continuous operation in demanding HVAC and process air systems where elevated temperatures can cause standard filters to fail. Designed for use up to 500°F (260°C), the DP® HT combines ultra-fine microglass fiber media with a high-temperature woven scrim backing to maintain filtration integrity in harsh environments.

Constructed with a durable aluminized steel frame and a heavy-duty expanded metal support grid, the DP® HT resists warping, corrosion, and mechanical stress. Each filter is precision-manufactured to maintain consistent pleat geometry, ensuring low pressure drop, balanced dust loading, and long service life.

Rated MERV 8 per ASHRAE 52.2-2007, the DP® HT is available in 1-, 2-, and 4-inch thicknesses and can be installed vertically or horizontally. Ideal for high-temperature air handling units, rooftop systems, built-up banks, and multi-stage prefiltration, it provides reliable, energy-efficient performance through Total Filtration Services (TFS).
