rrr fan overview
◆Series of fire-fighting high-temperature smoke exhaust fans have excellent performance and good high-temperature resistance , high efficiency, occupy less space than centrifugal fans, and are easy to install.
◆The series of special fire-fighting high-temperature smoke exhaust fans have passed the inspection of the National Fixed Fire Extinguishing System and Fire-Resistant Component Quality Inspection Center, and their performance has reached the leading domestic level.
◆Excellent high-temperature resistance: The fan test meets the requirements of fire protection standards. An enterprise internal control system that is higher than this standard is established to ensure that the system can operate continuously for more than 3 minutes under high temperature conditions of 3℃, and will not be damaged for continuous hours/times under ℃ temperature conditions. , widely used in high-end civil building ovens, underground garages, tunnels and other occasions.
◆Wide range of application: According to the different requirements of high-end civil buildings, variable speed or multi-speed drive can be used to achieve the purpose of dual-use in one machine (i.e. general ventilation and high-temperature smoke exhaust during firefighting). The blade shape is Axial flow type (-Ⅰ, Ⅱ) and oblique flow type (-Ⅲ, Ⅳ) make this series of fans have a wide range of performance parameters. If the user has higher requirements on noise, it can be made into a silencer type fan.
◆High efficiency: This series of fans is a new product developed using advanced software through multi-objective optimization design. Actual measurements have shown that the fan efficiency is greater than 1,000, and some large fans have a flat efficiency curve, which is conducive to energy saving.
◆Easy to install and occupy less space than centrifugal fans: The basic forms of this fan are axial flow fans and diagonal flow fans. They can be directly connected to the air duct or installed on the wall. The installation form can be vertical or horizontal. It saves floor space to a great extent
The meaning of the rrr fan model
.
The main technical parameters of the rrr fan
The performance selection and model description of the series of special fire-fighting high-temperature smoke exhaust fans< br/> ◆The performance listed in the fan performance table is the performance within the highest efficiency range, which is divided into five performance points according to the air volume. The selection shall be based on the performance table. The qualified quality of the fan shipped from the factory is that the total pressure value error does not exceed the rated air volume. The performance selection table shows the performance under the standard state. Regardless of the performance required by the technical documents or ordering, the standard state shall prevail.
◆Fan installation methods can be divided into horizontal and rooftop types. If you have special requirements for air volume, full pressure, installation size, etc., our factory will design and produce it separately for you.
◆-, - means normal pressure type fire-fighting high-temperature smoke exhaust special fans, the blade type adopts axial flow type: - (single speed) and - (double speed) -, - means medium-pressure fire-fighting high-temperature smoke exhaust Special fan, the blade adopts diagonal flow type: there are two types - (single speed) and - (double speed).
◆-It is a special silencer type fire-fighting high-temperature smoke exhaust fan. Users can use different types according to actual needs.
◆-Series of roof-mounted fire-fighting high-temperature smoke exhaust fans, users can choose smoldering fiberglass hood or steel hood according to actual needs.
