Gas springs for vacuum press membrane frames
Gas springs, also known as gas lifts or gas struts, assist with raising and lowering heavy vacuum press membrane frames. They reduce the effort required from the operator, support smooth frame movement and help hold the frame in the raised position during loading, maintenance and membrane replacement.
GL-10-21-550-600 gas spring
The GL-10-21-550-600 gas spring is designed for vacuum press frames that require 600 N lifting force. It has a 21 mm cylinder diameter, a 10 mm piston rod, a 550 mm extended length, a listed working stroke of 230 mm and M8 fittings.
- Lifting force: 600 N
- Extended length: 550 mm
- Working stroke: 230 mm
- Cylinder diameter: 21 mm
- Piston rod diameter: 10 mm
- Thread size: M8
Single gas springs and two-piece replacement kits
The gas spring is available as a single unit or as a matched two-piece replacement kit. When a membrane frame uses two gas springs, replacing both at the same time helps maintain balanced lifting force and consistent movement on both sides of the frame.
Compatible vacuum press models
The listed GL-10-21-550-600 gas spring is compatible with selected Felder, Griggio and Istra-A vacuum presses, including Felder MVP-300, Griggio GPM-300 and Istra-A VP-3000/4000, VPR-3000/3500, VPS-1500/3000, TF-160/300/350H and TF-300/350HV models.
Always compare the force, extended length, working stroke, thread size and mounting dimensions with the existing gas spring before ordering. Compatibility can depend on the press version and membrane frame configuration.
How to choose a replacement gas spring
Selecting the correct replacement requires more than matching the overall length. Check all key specifications marked on the existing gas spring or measure the installed component carefully.
- Required lifting force in newtons
- Extended and closed lengths
- Working stroke
- Cylinder and piston rod diameters
- Thread and mounting connection sizes
- Vacuum press model and frame configuration
Safe replacement and installation
Support the membrane frame securely before removing a gas spring. Gas springs are pressurised components and must not be opened, drilled, heated or damaged. Installation should be carried out by a qualified technician according to the equipment manufacturer’s instructions.
EU and worldwide delivery
Brevita supplies gas springs and replacement kits for vacuum presses throughout Europe and worldwide. If you are unsure about compatibility, provide the press model and the specifications or markings from the existing gas spring.
