Air amplifier

Optimal usage zone: 0 to 12% vacuum.
Maximum usage range: 0 to 15% vacuum.
Applications: TRANSPORT - DRYING - DEGASSING
Handling very porous, light-weight products: carpet, textiles, foam, etc
Transporting small objects: granules, grains of coffee, rice, paperclips, etc.
Smoke evacuation, degassing.

Types of vacuum pumps

· Version X, 50% vacuum
Optimal usage zone: 13 to 40% vacuum.
Maximum usage range: 0 to 50% vacuum.
Use of vacuum pumps creating 50% vacuum implies a high suction fl ow rate in relation to the pressure drop.

· Version T, 75% vacuum and N, 90 % vacuum
Optimal usage zone: 41 to 90 % vacuum.
Maximum usage range: 0 to 90 % vacuum.
The interest of the vacuum pump which can create a 90% vacuum is to generate a high vacuum and therefore a high force/surface ratio.

Applications: HANDLING - SUCTION - EMPTYING - DOSING

. Handling porous, semi-porous and air-tight products.
. Programmed operations.
. Air and/or liquid dosing.

- With version N, 90% vacuum:
Create a localized vacuum. Rationalize use of the vacuum in the machine functions using suction pads.

- With version T, 75% vacuum:
Create a generalized vacuum in suction tables and chambers.
Ejectors are very often integrated into automated handling equipment.

The optimal usage zones recommended above are the most adapted to the different types of technology. However they are in no way restrictive or limiting.

The notes are valid for both COVAL product groups: air amplifi ers and vacuum pumps and also apply to all products using the same technology, whatever their market name.
