Key Features & Benefits
• Heavy-Duty 3-Stage Filtration: Achieves 99.99% filtration efficiency at 0.01 micron. Stage 1 traps bulk water and large particulates; Stage 2 removes oil mists, ultra-fine dust, and atomized aerosols; Stage 3 completely strips away foul organic vapors and odors.
• Next-Gen Digital Air Quality Monitoring: Features a high-visibility digital monitor that continuously samples incoming air for toxic Carbon Monoxide (CO) levels.
• Fail-Safe Alarm System: Includes a piercing local audible horn and high-intensity visual light alerts. A built-in remote alarm jack lets you daisy-chain warning systems straight to workers isolated deep inside noisy or enclosed spaces.
• Dual Automatic Drains: The first and second filtration stages utilize automatic drains with external discharge tubes, dumping accumulated oil and water hassle-free without pausing operations.
• Contamination-Free Operation: Housed in a durable, safety-orange Pelican-style case designed exclusively to operate in the upright and closed position, shielding the internal filters and sensitive electronics from harsh jobsite grit.
