M7 relay expansion accessories, can be used to control AC or DC power supply smoke exhaust system, can also be used to control other circuits, used as M8, there are safety risks when operating high-voltage circuits, requiring professional operation; M8 valve expansion accessories, can be used To control the air compressor switch. but the relay module, air valve module and Door need to be purchased separately, not included in the product list.


When do you need air assist?

Air-assisted engraving or cutting can only be used for engraving or cutting that produces more carbonized substances. Generally, the depth of engraving is less than 1mm, and the cutting of plywood less than 2mm does not require air assist. A small fan can be used to blow off the smoke generated by the engraving. Air assist is not recommended when engraving images, and adding air assist at this time will destroy image details.

What kind of air pump is suitable for cutting?

The main meaning of air assist is to blow off the carbonized material produced by cutting, and the general oxygener and electromagnetic inflator have almost no meaning. only the pressure of the oil pump and air compressor (0.4-1.5mPa) has the effect of blowing away the carbonized material. but it should be noted that the air of the oil pump contains oil and cannot be directly used for the air-assisted module of the closed cavity, otherwise the oil will contaminate the lens, resulting in power drop or damage to the lens. The air pressure of the air compressor can be used for a short time with the closed cavity, but When used for a long time, the water-containing gas will contaminate the lens, cause the power to drop, and even damage the lens.
