I. Product Overview

 BF, DBF low-noise wind chassis is a new wind power source, compared with the commonly used ventilation equipment, with air volume, low noise, low power consumption, easy accessibility features to the site. Ideal for general plant, civil, scientific research and education series pressurized office building ventilation and air conditioning systems. Box frame with arc-shaped aluminum frame, box board for the dual board structure, the outer layer is produced Baosteel color coated, laminated for polyurethane foam, inner galvanized sheet, to further reduce noise.

 Second, product characteristics

 1, varieties, specifications, wind, air pressure a wide range of options.

 2, with a number of inlet and outlet position, the unit can be ceiling mounted, floor-mounted, easy to install at the same time conducive to engineering design.

 3, low noise centrifugal fan, the unit has a low noise, low vibration, air volume, small size.

 4, using stretch removable frame profiles, field removable, flexible placement.

 Third, the product process

 1. Impeller: blades, front disk, the disk Baosteel produced from high quality galvanized sheet stamping cutting, hydroforming, galvanized rivets the blade with the front and rear plate riveted. And by the significant number of hard-bearing balancing machine calibration, balancing accuracy G4.6 level and above.

 2, volute: side by Baosteel produced high-quality galvanized sheet stamping cutting, hydroforming. Snail plate Baosteel produced from high quality galvanized sheet cutting shears, with special beading machine beading and rounded, side seams and cochlear board connection, adding the desired spiral bracket.

 3, cabinet: Cabinet profiles of metal roll forming cold-formed unit, box board for the duplex structure, the outer layer of Baosteel produced by the high-quality color-coated material shearing, bending, molding, cabinets layer for high-quality galvanized sheet, middle filled with polyurethane foam, good silencing effect. Box board and assembly methods for embedded profiles, improve fan seal, box board to ensure that the muffling effect, reducing the amount of air leakage fan.

 4, Chassis: heavy-duty metal chassis fan Cold Unit stretch forming C-production. C steel is an excellent cross-section channel formed by the evolution of the mechanical properties of a new type of steel, good mechanical properties, elegant appearance.

 5, the access door: Fan belt with removable handle their maintenance and repair is extremely convenient.

 6. Assembly: After the fan assembly, X, Y, Z axis vibration velocity is less than 5.6mm / s.
