ZPA1-03-A / ZPA1-04-A / ZPA1-06-A
NANPU ZPA1 Series: Precision Air Filtration for Demanding Environments
Engineered for professionals, this three-stage filtration system (sintered, fine, and activated carbon) ensures ultra-clean air for water-based coatings and industrial applications. Built with a heavy-duty metal casing that resists temperatures up to 248°F (120°C), it delivers high-efficiency airflow (127 CFM at 9 bar) under extreme pressures. Whether for auto refinishing, woodworking, or industrial spray jobs, its robust design and modular flexibility make it a top-tier choice.
