About BKD
BK Roots Blower is a kind of product designed and manufactured
according to the national standards and by the techniques
introduced from American TUTHILL Co. This type blower is featured
with simple structure and high cubage efficiency.
BKD series is a dual stage roots blower, which has two BKWblowers
in series, can achieve higher pressure comparing with single one,
also there is a middle cooling system between the first and the
second stage, it ensures the standard temperature of the airflow to
the second blower.

Working Principle
Roots blower is a cubage blower, and it discharges a fixed amount
of air in proportion to its rotation speed. Every rotation, there
is two lobes to finish three times absorbing and dischargeing air.
Compared with two lobes blower, it is of less air pulses, smaller
load change, higher strength, lower noise and vibration.
Two paraller shafts have three lobes each, all the lobes keep small
clearance with each other and housing inside. Every lobes
rotatiomn, a certain air will be absorbed at inlet and transfeered
form the housing inside surface to blower's diacharge port.
Two shafts will be turned by the timing gears, no any touching
between lobes, so it can be turned at high speed without any
lubrication inside. It has the following chaaracteristics: simply
configuration; running smoothly;good performance stabilization. It
has been widely applied in various industries.
