24x24x12 Koch Multi-Cell High-Temp Synthetic Cartridge Filter, MERV 14, 750°F, Single Header, Model 110-776-001 (Each)

Description

This 24″ × 24″ × 12″ Koch Multi-Cell HT 750°F High Temperature rigid extended-surface filter (part number 110-776-001) delivers MERV 14 filtration in a single header configuration.

Why rigid filters matter for commercial HVAC

Rigid construction is essential for variable air volume (VAV) systems and any air handler where airflow isn’t constant. Non-rigid filters can balloon or collapse as airflow changes, creating bypass paths and defeating the filtration. Rigid filters hold their shape across the full VAV airflow range — Koch Multi-Cell is engineered specifically for this service.

Design and construction

• Construction: Aluminized steel construction rated for continuous operation at 750°F. Will not flake or embrittle in sustained high-temperature service.
• Media: Extended-surface pleated synthetic or microfiberglass (MERV-dependent), supported by rigid internal separators.
• Header: Single Header.
• Certification: UL 900 listed.
• Temperature rating: 750°F continuous.

What MERV 14 captures

Sub-micron particles including most smoke and bacteria-sized particles. MERV 14 is a commercial-grade filtration tier, typically used as final filter in commercial air handlers or as a high-efficiency upgrade in facilities with dedicated high-MERV systems. Standard residential HVAC equipment is rarely rated for MERV 14 static pressure.

Typical applications

Commercial office VAV systems, schools, hospitals, retail, and industrial HVAC. The HT variant specifically serves oven exhaust, industrial drying, kiln ventilation, and other sustained high-temperature applications where standard filter frames would fail.
