1.In accordance with DIN VDE 0105 and IGC 364, non-qualified personnel is not allowed to be engaged in electrical equipment work. Any qualifier has

to act complying to the strict standards.

2.This catalogue can not include all specifications, maintenance or installation. We hereby to insist that it is necessary to contact us when you

have questions which may come to you in any possible process.

3.A member of our team can assist you in determining what regenerative blower will meet your need. So we may request following information: airflow,

vacuum, pressure or onsite pictures. This is for selecting the optimized model which can meet basic need and can save energy as well.

4.When placing a PO, please attached with essential requirements with voltage included.

5.Regenerative blowers are designed for handling air and inflammable, non-corrosive, non-explosive gas. They are designed for continues use.

Applications involving frequent temperature changes should be evaluated by our technical department prior to confirmation of PO. It is also

prohibited to use in non-industrial installations and to carry out modifications to the machines.

6.The machines must be installed in an aerated place where the ambient temperature is between 5/104?. Treatments on the machine components are

needed whenever humidity exceed 80%. Make sure to leave at least 50cm around the machine in order to operate freely.

7.Pay attention not to confuse the suction and discharge piping. Install a filter for foreign object.

8.RESIDUAL RISKS

Improper use of regenerative blowers can cause serious injuries.

Danger is due to:

9.The WARRANTY period is: 12 months from the date of their initial use or 18 months from delivery, whichever expires first.

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.

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.
