GENERAL DESCRIPTION
The CentriMaster GTLB-1 and GTLF-1 are direct driven, single inlet
centrifugal fans. The range covers air flows up to 9 m3/s (32 400
m3/h) and pressure rises up to 3 000 Pa with GTLB-1 and up to
1.1 m3/s (3 960 m3/h) and pressure rises up to 1 600 Pa max
with GTLF-1. The fan series consists of centrifugal fans available
with two types of impeller:
• Impeller with backward curved blades for the GTLB fans
• Impeller with forward curved blades for the GTLF fans
VERSIONS
STANDARD VERSION
The GTLB-1 and GTLF-1 fans are rated for continuous operation
at temperatures up to +80° C if the inlet of the fan is connected
to the ducting. If the motor is exposed to the air stream, i.e. on a
free inlet fan, the ambient temperature must not exceed +40° C.
HIGH TEMPERATURE VERSION
The high temperature (HT) version is used for smoke extraction
purposes. It has been tested and certified to withstand 400 °C for
2 hours by SP Technical Research Institute of Sweden, conform-
ing with the standard EN 12101-3.
Only GTLB-1 fans are available as high temperature version.
See specification text on page 40.
ATEX VERSION Backward curved impeller Forward curved impeller
The ATEX version is used in potentially explosive atmospheres
according to Directive 2014/34/EU using Ex de motors.
Only GTLB-1 fans are available as ATEX version.
See specification text on page 40.

dynamic properties.
Fan impeller of the type GTLB fans Fan impeller of the type GTLF fans
FAN INLET
The fan inlet of a GTLB-1 fan is specially designed to ensure high
fan efficiency and low sound level generated by the fan. The inlet
cone is deep drawn in one piece and fastened to the side plate of
the fan casing.
Inlet cone of the GTLF-1 fans is deep drawn in the fan casing.
MOTOR BRACKET
The ATEX version of GTLB-1 has an inlet cone made of copper.
The motor bracket is made of Sendzimir galvanized sheet steel
and fastened directly to the fan casing.
