Side-mount electrical cabinet air conditioner NHP4350

compactindustrialfilter-less

Description
The NEMA 12 Non‑Hazardous Purge (NHP) Cabinet Cooler® PNHP series from EXAIR provides dust‑ and dirt‑resistant cabinet pressurization to prevent contaminants from entering electrical enclosures. Thermostat control limits compressed air use by activating cooling only when internal temperature approaches the setpoint (standard factory setting 95°F / 35°C, adjustable). Systems include a water‑dirt filter‑separator with automatic drain and a cold air distribution kit for effective internal airflow.
