Specially Designed to Spray Fireproofing Fiber

The Poly-Spray® C-500 fiber spraying machine meets the most demanding needs of professional fireproofing contractors, and can be used to apply sprayable fiberglass and cellulose products. Available in 10- and 15-horsepower configurations, it features a turbine feeder that provides better performance and smoother flow at the nozzle. The machines are powered by a single electric motor that drives the positive displacement blower and a hydraulic pump, which in turn powers a variable-speed hydraulic feed system. The machines are easy to maintain, requiring only common tools.

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.  

Panel-Mounted Voltmeter - Conveniently positioned to allow machine operator to monitor voltage.  

Voltage Bucking and Boosting System - Five-position switch enables operator to reduce (buck) or boost voltage during fluctuations. Switch positions are Nominal Voltage, 8% Buck, 16% Buck, 8% Boost and 16% Boost.  

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.  

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

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 protect the machine 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.  

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

Caster-Mounted - Heavy-duty casters make it easier to move machine closer to 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.
