ROBOX consist of the following units: Inlet silencer The inlet silencer consists of a patented, adjustable device that can be tuned in order to reduce the noise at blower's basic frequency through the interference phenomenon of sound waves, and of an absorptive device fading the noise frequecies over Hz.

The filter is positioned into the silencer, just robuschi robox blowers the blower inlet port, avoiding pollution of robuschi robox blowers gas even in case the absorbing material is damaged.

Robuschi robox blowers silencer The discharge silencer consists of a cross flow resonance chamber cutting noise frequencies over Hz, connected in series to a patented adjustable device reducing the noise at blower's basic frequency through the interference phenomenon of sound waves.

The discharge silencer has been robuschi robox blowers designed to reduce pressure losses in the conveyed gas flow.

The absence of deadening material prevents the gas pollution and guarantees steady, efficient operation of the silencer throughout the time.


The silencer body is a robuschi robox blowers of the baseplate, common to the blower and to the driving motor. Drive The V-belt drive robuschi robox blowers designed with a special patented device, supporting the motor on swinging brackets, which reduces loads on blower''s and motor''s bearings, assuring and keeping automatically the correct belt tension during operation, with no need of periodical adjusting.

In GRB packages V-belt drive is adjusted through a standard slide rails tensioning device suitable for motors up to kW. In CRB packages the drive is direct through a standard flexible coupling or through gearbox to suit motor robuschi robox blowers up to kW.

Safety Valve The safety valve limits the operating differential pressure value of the blower. It is made of G galvanized cast iron to make it weather-proof.

Check valve The valve prevents counter rotation of the blower when it is stopped under load. It is provided with a new disc in heat resistent rubber, reinforced with metallic core, which grants free gas robuschi robox blowers through its full open passage section, reducing pressure losses and avoiding disc clattering under low flow conditions.


Unloading valve The valve, available upon request, allows direct gas discharge during start up, in particular when using star-delta starters. Operation is fully automatic and does not require an electric actuator.

Electric control can be provided upon request, in case of special running cycles. Noise enclosure Noise enclosure allows to meet the most stringent noise specifications.


It is provided with self supporting, galvanized steel panels coated with polyurethane self extinguishing sound absorbing material. Two types of coating are available for parts in contact with the conveyed liquid casing, sides and rotors when aggressive: The consequent drain of exhausted For this reason several ROBOX evolution can be placed side by side thereby significantly reducing the space they require and therefore the dimensions of the blower room, thus also decreasing system costs.

Open the catalogue to page 8 Pressure - vacuum blowers ROBOX evolution offers robuschi robox blowers edge technology as for silent operation of low pressure compression unit. The emitted sound level is in fact 7 dB A lower than the previous series, in all robuschi robox blowers conditions, a result obtained thanks to a combination of innovative components: Direct relief valve for pressure operation.
