The first H1 Duct Truck ever made, this was the beginning of the revolutionary new Duct Truck design by Hypervac Technologies that forever changed the way Duct Trucks were made. On this first model of the H1, Hypervac got rid of the PTO drive system, added light weight aluminum construction, created an easy clean out bin and managed to cram in extra storage space as a result of the new design. Professional Air Duct Cleaning Equipment would never be the same.

The inside of the box is empty, the HAVAC gas powered vacuum system and the air compressor need to be added. Date Taken: July 31st 2013

Before powder coating, this is the rear view of the H1 box. The markings were made to smooth out any scratches on the aluminum. Newer versions had the doors on the back for better access to hose. Date Taken: July 31st 2013
From beneath the H1 Duct Truck it is clear that the improved design gets rid of the PTO once and for all. Aug 9th 2013
With the body complete, the HAVAC gas powered vacuum needed to be installed. Aug 9th 2013
Unique even for the HAVAC vacuum system, the first H1 had a diesel powered HAVAC unit installed. As with most HAVAC systems, all subsequent H1 Duct Trucks had smaller gas engines. This was done for three main reasons: convenient for trips to the gas station, extra HP was unnecessary, and it was easier/cheaper to operate and repair if necessary:

The T-take off eventually evolved after the first H1. Subsequent versions have the vacuum hose hookup coming out of the back rather than from either side. T-Take offs are still an option on the H1 or H2 Duct Truck, but not part of the standard design:

Finally, the very first H1 Duct Truck was completed. For the first time, all the new design features were available in the duct cleaning industry: a separate engine to power suction got rid of the PTO system, an easy clean out bin, lightweight Aluminum construction, enough storage for a portable duct cleaning vacuum and a separated air compressor.
The roof of the first completed H1 Duct Truck. A ladder rack was added, and subsequent versions had metal grip walkways on the roof, as well as a rear door for accessing the hose hook up from the back. Date Taken: Jan 10th 2014

Seen in this image, the hose storage is up front, and the diesel engine, unique only to the first H1 Duct Truck. Date Taken: Jan 10th 2014
After completing the first H1 Duct Truck, demand for the new design has grown due to the innovative changes made by Hypervac Technologies. Although the first H1 was welded together independently of Hypervac, today each Duct Truck is welded and bolted together in-house.
