OPERATION PRINCIPLE<br />
JH Series <strong>Roots</strong> <strong>Blower</strong> is a positive displacement, constant volume machine which operates against<br />
varying pressure. The two impellers which are mounted on parallel shafts, rotate in opposite direction and<br />
with every movement of the impeller across the blower inlet, a definite volume of air is trapped and carried<br />
across the casing to the blower outlet where the air is discharged. With a constant speed operation, the<br />
displaced volume is essentially the same at a constant pressure or temperature. Whereas increasing the<br />
speed of the blower against a constant pressure increases the volume of air delivery. In addition, the timing<br />
gear fitted in a blower control the relative position of the impellers to one another and maintain small but<br />
definite clearances. This allows operation without the need for lubrication inside the air casing.<br />
MAIN FEATURES<br />
§ Positive displacement blower with no compression, able to maintain a stable gas flow with very small<br />
variation in flow rate despite the changes in inlet pressure.<br />
§ Delivers a stable pressure pulses of air with linear type impeller and thus, reduces the noise level by 5-<br />
8 dB(A) lower than twin-lobe blowers.<br />
§ Special impeller of mesh curve and small enclosure making roots blower high efficiency, low energy<br />
consumption.<br />
§ Has longer service life with high precision synchromesh hard-toothed surface gears.<br />
§ Delivers clean pressurized air supply without any oil particulates.<br />
§ Features streamlined design, smart appearance, small size and light weight.<br />
§ Ease of installation and maintenance.<br />
APPLICATION AREAS<br />
§ Aeration in wastewater or sewage treatment plants<br />
§ Pneumatic conveying<br />
§ Oxygen supply for fish farms<br />
§ Filter flushing<br />
§ Plating Bath<br />
§ Drying processes<br />
§ Dust collection systems<br />
§ Sand blasting processes<br />
§ Grain handling<br />
