Multi-stage Centrifugal Blowers

Quick Overview :

SBSEnviro offers a full range of Multistage Centrifugal Blower (MSCF) with various models to choose from renowned brands.
Multistage centrifugal blower, based on the technology of welding multistage low speed centrifugal is a new generation high - efficiency product, gathering some patented technologies and longtime blower experiences of design and fabrication, which can satisfy users' appeal.

Most operators require blower that operates effectively and efficiently with very little daily supervision or maintenance.

There are two top brands on the global level, supplies Multistage Centrifugal Blower worldwide.

A) The Gardner Denver brands name has become synonymous with quality, reliability, and service.
B) Hoffman & Lamson brands are industry standards over 150 years. Proven reliability & performance in Industrial & process plants worldwide.

Operation Characteristic

Multiple impellers mounted on a single steel shaft.
A blower can be Belt drive, direct drive, Gear-Box, VFD.
Steam Turbine, Gas & Diesel Engines.
High turndown design to handle low flow requirements.
Maximum turndown up to 60% by Speed variation (VFD) or Inlet/ Suction Valve Throttling (IGV).

Noise : Below 85 dBA at 1 meter even without an acoustic enclosure.
Bearings : Only 2 bearings (Drive & Non-drive ends each). Antifriction Ball Bearings.
Lubrication : No additional operating cost for the lubrication system of the blower besides the cost of the oil itself.
Air Quality : Outboard mounted bearing design assure 100% lubricant-free air system.
Maintenance :
- A) Minor Maintenance : only Lubrication oil top-ups periodically (10-11 months), inlet filter cleaning/replacement.
- B) Major maintenance : Bearings replacement (10-12 years) & Labyrinth seals change (18-20 years) depend on suction media to handle.
Capacity Controls : Blower Controls can be by LCP (Local Control Panel) if supplied or existing plant DCS. For capacity control, the multistage design utilizes a dual method which again provide an additional safeguard to an operator to save power during low load conditions.
