Double Inlet THLZ PL Fan by Tecnifan-Comefri
backward curved centrifugal fan impeller
Designed for HVAC applications, high efficiency, compact design, low-energy consumption and quiet operation.
Main features
Double inlet centrifugal fans made of Z-275 galvanized steel sheet, with polyamide reaction impeller and forefinger technology.
The principle is to exploit the air swirls, always present inside a fan housing. As well known, the recirculation of the air streams inside the fan housing is a major source of losses, decreasing the fan efficiency and increasing fan’s noise. This device, called Forefinger ®, is actively readdressing this air recirculation to the outlet, with a systematic enhancement of the performances, both aeraulic and acoustic.
Free shaft outlet for pulley and belt drive. Features a double shaft end for easy mounting in eight possible orientations.
Construction
All fan housings are made of galvanized steel sheet and constructed using the Pittsbourgh sealing method, which guarantees a high-quality, airtight seal and a structurally reinforced housing.
This high-performance impeller is made of stainless steel, with welded, backward-curved blades. All impellers are coated with epoxy paint and balanced both statically and dynamically.
The impellers are attached to the shaft using a steel or aluminum hub. The hub bore is precision-machined and incorporates a key and locking screw.
The light series (L) is constructed with a cross brace. The semi-reinforced series (R) is constructed with side frames and a cross brace. The reinforced series (T) is constructed with a frame and bearing support.
