Key Features

Principles and Construction


The blower will be used when a large quantity of air is required at normal pressure 0.1~0.5 kg/cm2 and consists of the following main component units. Construction is simple, resulting in very little trouble.
  • Motor
  • Air chamber
  • Air filter
  • Base (and Oil tank)
  • Blower body
  • Oil dropping nozzle

The blower is so designed and constructed that air is sucked, compressed and discharged repeated
while vanes protruding from the grooves of rotor are coming in and out by revolution of a rotor
(rotating body) set eccentrically inside the cylinder diameter.
Friction heat is generated due to friction of iron and iron at rotating part and reciprocating part. Therefore, a minimum required quantity of circulating oil is dropped into the cylinder constantly while operating, by means of an oil dropping nozzle in order to make lubrication for the purpose of prevention of generation of heat and noise. Also, the oil works on increasing airtightness by coating over each part with itself.
There is automatic circulating equipment designed and manufactured by taking advantage of differential pressure of blower for circulation of oil.

Features of DISO Rotary Vane Blowers

Compact, powerful air flow rate and yet silent operating sound

Compressed air is produced by revolving movement. Therefore, DISO Rotary Vane Blowers display their powerful discharge capacity for their compactness. And yet, the operating sound is so small that machine room isn’t required for small capacity models. No large models require the soundproofing equipment in the machine room.

Very little vibration and simple installation and handling

In the case of small types, no vibration is generated at all. Mere installation of a rotary blower is enough to meet your requirements, not requiring tightening work with anchor bolts. No limitation is placed on installing place.

Strong against pressure change

For instance, if a DISO Rotary Vane Blower is used for sanitary treatment in the septic tank, almost no air flow rate is decreased even if load becomes large due to the change in the pressure inside tank.

 

Provided with an air chamber for carrying out air dispersion smoothly

All models are provided with an air chamber, resulting in being free from air pulsation and air dispersed smoothly.

High superiority for keeping always high performance

Highly durable materials are adopted for all operating parts and outside, including cylinders. DISO Rotary Vane Blowers are designed and manufactured very robustly as almost free from trouble and deterioration of performance after a long use.

Unique mechanism – oil dropping equipment

No oil choked, no oil scatter, and very little oil decrease by the unique mechanism – oil dropping equipment

Check valve built in (All type)

There is a check valve attached to prevent the back flow from the tank.

Air releasing valve built in (All type)

Provided with an air releasing valve which prevents the burning damage of a motor at the time of overloading that is clogging trouble of air dispersion pipe and which serves for an alarm whistle.

 

Applications

  • For sanitary treatment (exposure to the air) in the septic tank and for purification of water
  • For aeration in domestic and industrial waste water treatment plants
  • For agitation in plating tanks and water treatment tanks
  • For spraying for heavy oil and kerosene oil burners
  • For breeding and propagating fish in water tanks for tropical fish and fish ponds

The purpose of Slider Kit is to gather common slideshow-like jQuery functionalities (such as news sliders, photos galleries/sliders, carousels, tabs menus)

When tracking mouse movement, you usually need to know the actual position of the mouse pointer. The event object that is passed to the handler contains some information about the mouse coordinates.
