Efficient and low-noise fan HL3-2A Francis Francis low noise, energy-efficient fans and Francis PYHL-14A low noise, energy-saving fire temperature exhaust fan, is between an axial and centrifugal fans between new Francis fan blower manufacturers, compared with the same amount of wind gauge large centrifugal fans, axial flow relatively high pressure fan, with high efficiency, energy saving, low noise, easy installation. Unique fan design PYHL-14A type: high temperature closed built-Francis fan motor, arranged a special motor cooling system to reduce the ambient temperature of the motor. Francis fan performance of selected fan performance tables in performance review, performance listed in the table is the most efficient performance within the range, according to the characteristics of the flow is divided into five Heilongjiang Francis fan, according to prevail in the selection of the performance table, the factory fan Qualified performance under full pressure rated flow value does not exceed ± 5%. Performance selection table is a performance standard state, boring technical documents or performance requirements are standard state order prevail, the standard state atm = 101325Pa, t = 20 Ψ = 50% relative humidity of the air condition, when under actual conditions of use and above according to the relevant formula is not in line with the conversion, fan installation can be divided into vertical or horizontal Urumqi Francis fan, as installed in the order indicated in the vertical, such as flow, pressure mounting dimensions and other performance parameters have special requirements, the company will you separate design and production. Urumqi Francis fan | Francis fan | Air conditioning is provided by Wu Rui Ding Ding Rui City Air Conditioning Equipment Co., Ltd. Wu Cheng Ding Rui Air Conditioning Equipment Co., Ltd.
