HL3-2A mixed flow and low noise boiler fan/flow-mixed fan

HL3-2A/PYHL-14 ventilators ,designed according to "Quasi-ternary" flow theory,are made up of linear canister,conical hub,twist blades.Its inlet is matched with slip ring or arc noise elimination equipment.When the size is same,Its  pressure is higher than axial-flow ventilator's,and its air volume is larger than centrifugal fan's.Its features are high efficiency,compact structure,low noise,small volume.convenience for installation,etc.

This kind of fans are widely used in hotels,restaurants,stores,office buildings,gymnasium,etc to ventilate.It's also used in pipeline and mining industry to increase the pressure and exchange air.
