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. 

Air Bleed System with Panel-Mounted Gauge - Allows for variable control of air volume to aid in fine-tuning of the air-to-material ratio.  

Four-Speed Transmission - Allows the operator to vary speed of all internal hopper components and air-lock feeder for additional control of the air-to-material ratio, for optimum material performance. 

Material Control Slide - The easily adjustable 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

Heavy-Duty Electric Clutches - Dependable 12-volt brushless clutches offer a long service life. The clutches allow for independent control of air and/or fiber flow.  

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. 

Automatic Pressure Relief Valve - Factory preset valve protects the positive displacement blower from pressure spikes.  

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 - Special, easily replaceable shear keys offer protection from damage by foreign objects.  

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.  

Quick-Change Seal System – Optional on the Volu-Matic® V, the Quick Change Seal System allows quick access to the air-lock feeder rotor for inspection and replacement of seals. 

Built-In Water Pump - Standard on the Volu-Matic® V and available for most machines, the built-in water pump is used to supply water and/or adhesive to the spray nozzle at the point of application. 

Hopper Extensions - Increase capacity of standard material hopper. Frees up person in truck to do other tasks while hopper is emptying.
