SCOPE
This GBHE Engineering Guide provides information to assist in preparing an
estimate for the cost of single stage, integrally geared, turbo-blowers. The data
contained is based on analysis of past purchases for projects and offers by
vendors.

Calculate
2.2
Obtain Basic Cost from Fig 1
The basic cost is for a single stage, integrally geared blower operating
beyond the limit of an arduous duty fan and constructed in standard
materials of construction, i.e. cast or fabricated steel casing, forged steel
welded impellor, steel shaft running in plain bearings.
