Centrifugal Inline Square (CIS)
YORK® Centrifugal Inline Square (CIS) fans are ideal in square ducts as clean air boosters in supply and exhaust systems where conventional blowers are impractical.
- Square, inline duct mount
- Direct or belt drive; ECM option
- Inlet filter box with 1" or 2" filters
YORK® CIS fans have a compact design that gives designers an excellent alternative to conventional blowers.
Wheel construction is spark-proof and noncorroding, and produces reduced motor starting torque and aids in long bearing life.
