The vacuum is generated from the existing airline. Other methods of mounting are by a wedge arrangement or a quick release clamp is available for some vibrators.
Vacuum Fixing Devices for Vibrators - VAC Series
Quick mounting without bolting or welding
Strong connection due to high vacuum
Can also be used on curved or uneven surfaces
Optional air economizer
ATEX conform and stainless steel versions available
Customised versions possible
Applications The vacuum fixing devices series VAC are designed to allow quick attachment of vibrators to smooth or, under circumstances, uneven and curved surfaces. A special feature of the the vacuum fixing is the ease of attachment, which requires no welding or bolting.
Construction and working principle The appropriate vibrator is screwed to the vacuum fixing and connected to the supply hose leading to the hand valve. As soon as the vacuum fixing is connected to the compressed air supply, the unit is sucked tightly to the mounting surface, thus ensuring a strong connection between the vibrator and the surface. The air economizer "S" creates a reduced vacuum, which is sufficient to clamp the vibrator when it is not running and which reduces the air comsumption by over 30%.
When the vibrator starts, the fixing device automatically produces the full vacuum. ATEX conform vacuum fixings series VAC and units with a stainless steel plate are available.

Vibration Systems & Solutions | Flow Aid Solutions
For over 40 years we have supplied flow aid solutions to keep product moving from hoppers, bins and chutes. Whether pneumatic rotary, pneumatic linear or electric rotary, the right vibrators, mounted correctly, will give just the right force to move your product smoothly and effectively. Damage to bins is eliminated and a continuous flow of product is assured. Nothing is added to your product stream, as in the case with air injection devices.
Operator "damage" is eliminated with no more hammer swinging, and noise is down to acceptable levels with most vibrators, usually far lower than noise levels of other flow promoting devices.
Vibrator mounting is non-invasive and doesn't require the cutting of your bins, with the subsequent clean up costs and risk of product contamination. There is no need for installation technicians to enter the hopper. Vibrators can often, depending upon the product, be installed without any interruption to your process.
Many types of vibrators are also used as drives for vibrating feeders and vibrating tables, especially pneumatic linear models which have very good control features.
