TPI Corporation Heater 208V/240V 1 Phase Multi Watt Fan Forced Unit

Description

Protect worker lungs and maintain strict negative air pressure inside containment zones with the compact Dri-Eaz DefendAir 400 Air Scrubber on remediation sites. This portable unit filters 400 CFM through true HEPA media. It uses dry filtration stages, requiring you to keep the unit clear of standing water puddles and wet spray slurries.

Rotomolded high-density polyethylene constructs the durable suitcase housing shell, resisting impact drops, water corrosion, and jobsite scratches. A continuous-duty electric motor draws 2.8 full-load amps on standard 115V 60Hz single-phase wall circuits, driving a backward-curved motorized impeller. Total dry bare tool weight measures 34 lbs. Exterior dimensions measure 21 inches long, 19 inches wide, and 16 inches tall with an integrated carry handle.

Key Features of Dri-Eaz DefendAir 400

Mold remediation contractors buy Dri-Eaz DefendAir 400 scrubbers to establish clean room containment zones and scrub fine drywall sanding dust. Equipment pricing delivers certified HEPA filtration in a compact rotomolded case that fits through tight attic crawlspace entries.

• Certified true HEPA filtration media captures 99.97 percent of microscopic particles down to 0.3 microns.
• Variable-speed control dials adjust process airflow from 250 up to 400 CFM for precise room air exchanges.
• Two-stage pre-filter pads catch coarse gypsum dust and pet hair to extend expensive inner HEPA filter life.
• Rotomolded polyethylene housing shells survive rough truck transit, stairs, and construction drops.
• Integrated auxiliary daisy-chain GFCI outlets allow linking up to four units on a single 15-amp breaker.
• Built-in eight-inch duct collars hold flexible lay-flat ducting for negative pressure exhaust containment.
• Molded top carry handles balance tool weight for one technician climbing ladders or entering crawlspaces.

Air Filtration Static Bench Metrics

Bench testing with fresh filters installed confirms 400 CFM output on high speed against 1.6 inches of water-gauge internal static resistance. Laser particle counter tests confirm 99.97 percent capture efficiency on 0.3-micron aerosol challenge testing. The motorized impeller draws 2.6 running amps on 115V lines with zero motor overheating. Operating sound meters record 63 dB at ten feet away. Rotomolded cabinet seams maintain an airtight seal up to 2.8 inches of static water-gauge negative pressure with zero air bypass.

Remediation Handling Realities Maintenance

Carrying this 34 lb air scrubber into containment areas takes one technician using the molded suitcase handle. Changing filters takes hand pressure on the top quick-release latches without tools. Do not buy this air scrubber for volatile chemical vapors, hot metal grinding sparks, or wet paint overspray booths.

• Replace the paper pre-filter pad after every dirty drywall sanding or mold remediation shift.
• Vacuum the secondary carbon pleat filter face using a soft brush nozzle once each week.
• Replace the primary HEPA filter cartridge whenever the filter change indicator light remains lit.
