In order to save everyone’s time, but also to prepare for the pre-ordering of the automatic rolling filter. Knowledge is popularized, and the following text is specially compiled for reference:

One of the preparatory work: determine the required air volume, design wind speed: this is the primary task for quotation of the roller shutter filter, and it is the basis for our staff to select and quote. We will according to the design requirements of air volume and wind speed, according to the calculation formula Calculate the suitable automatic rolling filter size, and then calculate the filter price. So please customers, don’t just come up with how your automatic rolling filter is sold, at what price, the price of this non-standard customized equipment depends entirely on the size and requirements, there is no general price.

Preparation 2: Determine the input power supply on site: The input power supply has little effect on the price, but it affects the ordering of the motor equipment. If the motor is not required to be three-phase or single-phase, we will supply it in accordance with the standard three-phase package. If the site conditions are restricted, there is no supply of three-phase power, and special wiring is required, would it not be a waste of manpower and material resources, and the gains outweigh the losses.

Preparatory work three: Determine whether there are corrosive gases and substances on site: The filter media situation on site determines the material selection of our automatic rolling filter. In ordinary environments, we only need to use the material of the cold-rolled steel plate baking varnish. For media with corrosive gas, we will recommend customers to choose the whole machine stainless steel SUS304. As for some special environments, such as the heavy salt spray at the seaside, we will use SUS 316 stainless steel. If the anti-corrosion level is high, even the housing of the motor is made of SUS316. The switch housing, pipe fittings, bolts, etc. will be strictly processed.

Preparatory work four: Determine whether there are flammable and explosive gases and substances on site: If there are flammable and explosive gases on site that may cause explosion hazards, we will recommend customers to choose the explosion-proof treatment of the whole machine, supporting professional explosion-proof motors and explosion-proof electric control boxes , Explosion-proof wiring measures are handled, and the potential hazards of explosive gases are strictly minimized. Our company has successfully mass-produced explosion-proof roller shutter air filters in chemical plants and waste gas treatment industries.
