ATMV/ATMVC Heat-Resistant HEPA Filter (350°C)
Product Overview
ATMV/ATMVC is a heat-resistant HEPA filter for continuous 350°C service (peak 400°C × 1h), with 99.99% efficiency @ 0.3 μm. Built on a stainless-steel separator-type frame and reinforced with stainless-steel mesh for higher mechanical strength than ATMCU — ideal for applications with elevated face velocity or vibration.

Applications
- HEPA downstream of nuclear ventilation blowers - Terminal filtration on vibrating high-temperature equipment - Power-plant high-temperature high-velocity airflowSelection Notes
- For static depyrogenation tunnels, ATMCU is more economical. - For vibrating or high-velocity applications, choose ATMV/ATMVC. - **150 mm (Q) / 290 mm (P)** — select by airflow demand.Selection References
Before ordering, verify the efficiency grade, media type, and whether the operating environment fits your requirements.
