FESTO Other: Air Reservoirs and Accessories

What does this category contain?

Besides drives, valves and air preparation, every pneumatic system needs a number of supplementary components. This category brings together such FESTO products. They include VZS and CRVZS air reservoirs, which act as a local air supply to compensate for pressure fluctuations and cover brief peaks in demand, and silencers such as U and UOS that reduce exhaust noise from valves. Optical pressure indicators and indicator plates for signalling switching status as well as end plates for manifold rails complete the range. These small parts are frequently needed during modifications and repairs, so they should be planned and procured together with the rest of the pneumatics to avoid delays in completing or restarting a machine.

Selection criteria and versions

• Air reservoirs: choose volume and port thread to suit air demand; the volume is part of the type code, e.g. CRVZS-5 or CRVZS-20. The CR prefix denotes corrosion-resistant versions.
• Silencers: thread size and flow rate to match the valve exhaust; high-attenuation versions for noise-sensitive workplaces.
• Pressure indicators: for visually checking whether a line or control circuit is pressurised.
• End plates: for closing unused ends of manifold rails.

Frequently asked questions

When is an air reservoir useful?

When more air is needed briefly than the supply line can deliver, or when pressure drops at large consumers must be avoided.

Which silencer fits my valve?

The thread of the exhaust port is decisive. Also make sure the silencer does not unnecessarily restrict the valve's flow.
