NIKRO PDU4000 Upright Dual Motor Duct Vacuum – 5000 CFM, HEPA

NIKRO PDU4000 Dual-Motor Upright Duct Vacuum for Restoration Crews

The PDU4000 runs two motors through a single upright cabinet to pull heavy debris out of duct runs at 5000 CFM. Its three-stage filtration ends in a 99.97% HEPA filter rated to 0.3 micron, so the dust it collects stays inside the machine. The upright footprint keeps the unit on a smaller floor area than a stacked multi-cabinet system.

PDU4000 Dual-Motor Pull and HEPA Capture

Two backward-incline blowers give the machine the airflow to clear packed ductwork in one pass, and the sealed filter train holds the fine particulate the job is meant to remove. Because both blowers feed one HEPA-sealed cabinet, the soot and dust pulled from the ducts stay inside the machine instead of drifting back into the space the crew is cleaning.

• 5" static pressure moves debris through extended duct paths
• 115V/10 on each motor runs off two standard plugs
• Upright cabinet, 31" L x 21" W x 47" H fits tight mechanical rooms

PDU4000 Applications and Environments

Duct-cleaning contractors run the PDU4000 through commercial HVAC systems in office towers, hospitals, schools, and hotels where return air carries years of settled dust. Restoration crews bring it into fire and water losses to strip soot and debris from ductwork before a building reopens to tenants. Facility managers keep one on hand for scheduled maintenance across apartment complexes, retail centers, and municipal buildings with long duct networks. Because each motor runs on a standard 115V circuit, the unit powers up in most mechanical rooms without a generator, and its 207 lb rolling frame moves up service elevators and through standard doorways from one floor to the next.
