FRP / GRP Centrifugal Blowers
Table of Contents
FRP / GRP Centrifugal Blowers are corrosion-resistant air handling equipment’s designed for extraction and conveyance of chemically aggressive gases, fumes, and industrial exhaust streams. These systems are extensively used in scrubber systems, chemical plants, electroplating units, pickling lines, and pollution control installations where conventional metallic systems fail due to severe corrosion exposure.
SREX Composites Private Limited is among the leading frp blower manufacturers offering advanced and high-performance frp blower, frp centrifugal blower, frp centrifugal fan, frp fan, grp blower, and grp centrifugal blower systems engineered according to required airflow (CFM / CMH), static pressure, gas composition, process conditions, and operating temperature.
Our product range includes specially engineered thermoplastic dual laminate blowers such as pp frp blower, pp frp centrifugal blower, hdpe frp blower, pph frp blower, upvc frp blower, cpvc frp blower, pvdf frp blower, ectfe frp blower, fep frp blower, and pfa frp blower for highly corrosive industrial environments.
As an experienced pp blower manufacturer and trusted pp frp blower manufacturer, we also manufacture advanced dual laminate systems including hdpe frp centrifugal blower, pph frp centrifugal blower, upvc frp centrifugal blower, cpvc frp centrifugal blower, pvdf frp centrifugal blower, ectfe frp centrifugal blower, fep frp centrifugal blower, and pfa frp centrifugal blower for severe chemical-duty applications.
Within this product category:
- FRP / GRP ID Fan (Induced Draft Fan)
- FRP / GRP Exhaust Blower
are specialized configurations of FRP / GRP Centrifugal Blowers designed for specific industrial airflow and ventilation duties.
FRP / GRP Centrifugal Blower
FRP / GRP Centrifugal Blowers operate on the centrifugal principle, where gas enters axially and is discharged radially at increased velocity and pressure. The casing and impeller are manufactured using corrosion-resistant resin systems such as Isophthalic or Vinyl Ester resin depending on chemical exposure conditions.
SREX manufactures premium-quality frp blower, frp centrifugal blower, frp centrifugal fan, frp fan, grp blower, and grp centrifugal blower systems suitable for industrial ventilation, corrosive gas handling, and pollution control applications.
Impeller designs include backward curved, forward curved, and radial blade configurations selected as per process duty requirements and operating parameters. These systems are engineered for long service life, high efficiency, and reliable industrial performance.
