HEPA-AIRE® H4500IV
|
For High-Performance Commercial Duct CleaningThe dual motor/dual blower HEPA-AIRE H4500IV Portable Power Vacuum is the most powerful unit available for commercial and industrial duct cleaning contractors. Based on the design of the highly successful and field-proven H2500IV IntelliVac, but with two high-efficiency motors, two AT Gold high-performance blowers and two Variable Frequency Drives, the H4500IV has all the extra vacuum power to handle your toughest and largest projects. Even with all of this power, the H4500IV is exceptionally maneuverable. Its patented four-module design enables the user to quickly detach one or more of its lightweight upper modules from the main power module and hand carry them. Advanced electronic controls provide soft starts and smooth, efficient operation on two 120 volt, 15 or 20 amp electrical circuits. |
The Portable Powerhouse for Commercial Jobs

Product features of the H4500IV include:
- Dual high-efficiency motors and our exclusive high-performance, backward-curved AT Gold blowers create exceptional airflow and static lift
- Requires only two 120 V, 15 or 20 amp circuits for operation
- Dual microprocessors “think on the job” by monitoring filter loading, voltage input and amperage draw and automatically adjust blower speed to provide maximum output within safe levels of electrical circuit for each motor/blower unit
- Advanced electronic system controls with two Variable Frequency Drive (VFDs) provide pre-programmed “soft-starts” and operator amperage adjustment to maximize vacuum performance without over-amping the supply circuit
- Recessed covered control panel with hour meters, amperage adjustment dials and meters, circuit breakers, filter loading gauge, and audio and visual filter loading alarms
- Stainless steel cabinet projects a professional appearance, resists corrosion and is easy to clean
- High-capacity, three-stage filtration system: Washable and reusable filter bag; MERV 11 pleated bag filter; and 99.99% efficient HEPA filter
- Patented four-module design quickly detaches into separate units and can be hand carried by one person
- Built-in stair climber, swivel wheels and 10” smooth rubber tires make transport a breeze
- Compact, upright design enables the H4500IV to fit through standard doorways
- Extra vacuum power and large dirt-holding capacity for commercial and industrial duct systems
