NIPPON MUKI
CKR Heat-Resistant Pre-Filter (450°C)
Product Overview
CKR is an ultra-heat-resistant pre-filter rated for continuous 450°C service, primarily used in automotive paint-booth and combustion-exhaust applications. Heat-resistant non-woven media captures coarse particulates such as paint overspray, carbon particles and ash.
Key features
・Continuous operation up to 450°C
・Effective coarse particulate capture
・Designed for paint booths and combustion exhaust
・Non-woven media, easy replacement
Target industries：Building, Medical, Food, Pharmaceutical, Electronics, Power generation, Nuclear power

Detailed Description
CKR is Nippon Muki’s high-temperature pre-filter for automotive paint-booth ovens, protecting downstream HEPAs from heavy paint-overspray or carbon-particle loading. The 450°C rating also suits post-combustion exhaust pre-treatment.

Applications
- Automotive paint-booth drying ovens - Coarse filtration on combustion exhaust - Air handling near boilers in power plantsSelection Notes
- Specified by face velocity (m/s), not volumetric CMH. - Service life is short due to high dust load — pair with differential-pressure monitoring. - Always install a downstream heat-resistant HEPA (ATMWC / ATMCU).Selection References
Before ordering, verify the efficiency grade, media type, and whether the operating environment fits your requirements.
