Details
Filtered & Lubricated Air.
40-80 PSI depending on model. 46-67 CFM.
Maximum Ambient Temperature = 200°F (93°C).
Selection based on the weight of the material in the sloped portion of the container.
Select the high frequency vibrator capable of producing a force equal to one-tenth the weight of the material when the vibrator is operating at medium pressure (40-60 PSI / 2.8-4.1 BAR).
For concrete consolidation, the selection depends on the consistency of the concrete.
Manual Valves
- 2-way manual ball valve used to turn the vibrator on and off for normal operation.
Solenoids
- For remote or automated control, use 2-way normally closed solenoid valve to turn the vibrator on and off for normal operation.
Airline Kits
- Required for trouble-free operation and long life of high frequency dual roller vibrators. Includes airline filter, lubricator, and pressure regulator with gauge.
Universal GCL Bracket
- Heavy-duty bracket used to mount portable GCL models on hopper or forms. Has special swivel nut that lasts longer and helps hold the vibrator tighter than regular nut and flat washer.
Special Brackets
- Provides wedge mount for railcar pockets for GCL models.
Sirometer
- Convenient, compact RPM Meter for measuring vibrator speed.
Produces Uniform, Directional Flow. High Frequency and High Amplitude Vibration. Versatile - Easy to control force and frequency by adjusting air supply. More Reliable Start-up - Dual-roller design assures fast, reliable starts every time. Single roller designs are frequently hard to start. No Bearings or Motors - means reliable performance, lower maintenance costs, and simple, easy operation. Fully Portable - GCL model is portable and can easily be moved from form to form. Fits standard mounting brackets. A convenient handle allows easy and safe transport. Rigid Mounting technique - Provides secure mount for maximum safety and performance. Most Rugged & Wear Resistant Available - Only two moving parts are the two hardened steel rollers. The steel shaft is hardened and ground for long life and even wear. Extra short bolts screw directly into the housing instead of long through bolts that break more easily. A single piece shaft with a hose barb on one end lasts longer than conventional two-piece shafts that can fret or rust. Inside cover surfaces are chrome plated for longer life. Easy repair and maintenance - Global offers replacement parts and an extensive rebuild program that refurbish the vibrators to like-new condition. This can significantly reduce the cost of ownership by extending equipment life. Five Year Warranty.
