The premier multifunction machine

The revolutionary Multi-Matic™ wall spray system is specifically designed for cellulose sidewall spray and dense pack/cavity fill applications. The system includes the Multi-Matic machine and the Multi-Tank ™, a 250-gallon heated and insulated stainless steel water tank (sold separately). The Multi-Matic sprays cellulose insulation into the wall cavity, recovers excess material - using a vacuum system - and returns it to the holding hopper where it is metered into the flow with new insulation and sprayed into the next cavity.  

The Multi-Matic system will fill a standard 16-inch-wide by 8-foot-tall wall cavity in 20 seconds or less while still providing the yield recommended by the material manufacturer. Operation of the system requires a minimum of two individuals, but it's designed to optimize spraying efficiency while minimizing the time required to set up and take down the equipment.

The Multi-Tank is 250-gallon heated and insulated baffled tank with corrosion-resistant valves, fittings and strainers. The pump, pump motor, and hoses are enclosed in the tank to prevent freezing. Click here for more information on the Multi-Tank.

Feature Details:

Fully Sealed Blow-Through Air-Lock Feeder - The steel feeder has one-piece seals around all three sides of each rotor blade to create a tight seal under pressure and help eliminate wear in the feeder housing and ensure a more consistent flow of fiber. The machine is designed to blow through each chamber of the air-lock feeder to put insulation material directly into the airstream. 

Positive Displacement Blower - The blower automatically increases pressure to the limit of the blower relief valve to prevent plugging of the hose. 

Material Control Slide - This device is controlled from the front panel on most machines. The ability to vary the slide position provides additional control of the air-to-material ratio.  

Heavy-Duty Gearboxes - Synthetic lubricants provide long, dependable life to the heavy-duty gearboxes.

Integrated Vacuum System - The built-in vacuum system returns scrubbed and recycled material to the machine for remix into the blend in wall spray applications.

Expanded Hopper - Large capacity hopper holds more material, allowing the operator in the truck to perform other tasks while the hopper is emptying.  

Automatic Back Flow Check Valve - The check valve in the air line between the blower and the feeder keeps material from being forced back into the blower by back-pressure when the machine stops blowing. 

Electrical Overload Protection - All machines are protected by circuit breakers sized for the individual circuits. The circuit breakers are designed to be reset should a trip occur.  

Mechanical Overload Protection - Hydraulic relief valves protect the Multi-Matic from damage caused by foreign materials.  

Self-Aligning Sealed Bearings - High quality bearings are used throughout the CertainTeed Machine Works product line. They are sealed to keep out dust and equipped with grease zerks for proper maintenance.  

Adjustable Drive Belts - Special belt-tightening screws make it easy to keep the belts properly tensioned as they wear.  

Wired Remote Control - A wired remote is supplied for machine control at the point of application. 

Integrated Safety Features - Front, rear and side guards surround all moving parts. In addition to an electrical interlock that disables the drive mechanism when the front safety guard is opened, emergency stop switches are standard for additional protection.  

Wireless Remote Control - A wireless remote control is available as an option on all Unisul and CertainTeed Machine Works machines.
