Usually our blowers do not require maintenance. Wearing parts service life(bearing and filters) depends on operating conditions. All machines have pre-lubricated bearing with a minimum service life of 12, 000 hours.

During usual operation (fluid inlet and ambient temperatures not exceeding 40?, differential pressure as per nameplate data), the following routine maintenance activities have to be foreseen.

CLEANING

Make sure that the machine is shut down and locked against inadvertent start-up. Clean the external part of the machine with compressed air. Deposit of dust on external blower surface avoid an adequate thermal exchange and can cause an overheating of the interior.

Clean the ventilation grid of the motor fan cover. Dirt on motor fan cover reduces the air flow and causes motor over- heating.

Every 10/15 days during operation it is advisable to clean the filter cartridge. If the machine operate in a high dusty environment, it is necessary to replace it frequently. A dirt cartridge increases the pressure differential, the absorbed power

and the operating temperature.

If the machine does not produce any differential pressure, or too low pressure, or gas flow decreases, it is necessary to clean the inside of the machine. 

Sealing rings and bearings replacement 

The sealing rings lose the sealing capacity when exceeding their lifetime(max 2 years), thus allowing fluid losses. At that extend, sealing rings must be replaced.

Malfunctioning occurs when the bearings exceed their lifetime(max 2 years) causing excessive noise. At that extend, bearings must be replaced.

Early wearing of bearings may be due to:

-Mechanical shocks during running or stop that can damage the ball rolling track.

-Running conditions over the limit of the nameplate causing temperature increase lubrication grease damage.




          






Connect the machine to the piping system by flexible connectors, avoiding rigid connections that may cause mechanical strengths and cause harmful vibrations.

The connection pipes must not overload the silencers.

Only remove the sealing plugs immediately before connection.

It is necessary to dismount the flanges in order to connect the accessories.

Choose adequate accessories and correct size of pipes in order to avoid performance losses.

-It is not advisable to install pipes with a diameter smaller than the inlet/outlet connections, in order to avoid obstruction and overloads;

-The manifold and the main piping must be adequately dimensioned when machines are installed in parallel;

-High radius curves pipes should be preferred to elbows;

-Do not install valves with internal passage lower than port nominal diameter and spring mounted check vales (performance losses are lower with clapet valves);

-In case of installation for air distribution, low resistance diffusers shall be preferred.

It is advisable to install a safety valve to avoid pressure overloads.

Connect the motor and check the rotating direction before piping connection.

The shaft direction of rotation is marked by an arrow on the fan guard of the electric motor.

The gas delivery direction is marked with arrows on both suction and discharge connections.
