Boxxer 427

Setting a new standard in performance and economy, the 427 runs with perfect alignment, less vibration, less noise, and less unwanted heat. HydraMaster raises the bar yet again, for truckmount construction.

Introducing the BUCS. Patent-Pending Coupling System

The Engine and Vacuum Blower of the 427 are joined by using a precision cast aluminum housing designed just for that purpose. The BUCS. coupling works like an automobile engine that is bolted to the transmission making one rigid assembly. It has many advantages.

• Longer life without maintenance or failure.
• The precision fit of the coupling ensures perfect alignment every time no matter how many times it is assembled.


• Perfect alignment means less vibration, less unwanted heat and less noise.
• Coupling element can be serviced without disassembly or loosening of Motor or Blower.

Advanced Blower Technology -- Premium Tri-Lobe Dominator. Vacuum System

The modified Tuthill 4007X Tri-lobe Blower, another exclusive to HydraMaster, has a .true. CFM capability of 391 CFM at 10. Hg or 446 CFM at 2. Hg. Simply put, the operational displacement of this blower ranges in the .superior. category. AND unlike other powerful blowers, it incorporates patented noise-reducing components, allowing for a much quieter operation. Further modifications provide for increased heat output to the heat exchangers.

Maintenance is simplified with a quick, easy sight-glass verification of oil levels, and our oil bath lubrication system on both sides means less maintenance and no messy grease weeping of the blower. [ More details...]

This 27 HP Briggs & Stratton engine supplies power with a purpose. The engine operates at only 64% of its capacity, and runs at optimum RPM for lasting performance and improved overall engine life. You'll have no worries about over-working this machine. The ported cool-air induction system reduce

The Boxxer's Last Step Chemical Injection System protect the unit's exchangers from chemical damage and helps control chemical waste. Last-Step Chemical Injection means no chemical passes through the water pump or heat exchangers. The unit's adjustable heat feature allows you to fin connected to a water supply to do extended flood extraction work.

Another advantage of the Boxxer is the ability to clean upholstery in "divert mode." Cleaning temperatures of 180 to 200 deg. F can be selected without dumping water into the recovery tank.
