The invention provides an air filter for an air compressor, which comprises a shell, wherein an air inlet cover is arranged at the upper end of the shell, an air outlet cover is arranged at the lower end of the shell, a silencing layer is arranged in the middle of the shell, a first filter layer and a second filter layer are respectively arranged between the silencing layer and the air inlet cover as well as between the silencing layer and the air outlet cover, air inlets are arranged at two sides of the air inlet cover, an air conveying port is arranged in the middle of the lower end of the air inlet cover and connected with the upper side of the first filter layer, an air conveying port is arranged in the middle of the lower end of the silencing layer and connected with the upper side of the second filter layer, an air conveying port is arranged at two sides of the upper end of the air outlet cover and connected with the lower side of the second filter layer, an air outlet is arranged at the lower end of.
The further improvement lies in that: the muffling plate is provided with baffle plates in a staggered manner.
The further improvement lies in that: the inner sides of the first filter layer and the second filter layer are both provided with an activated carbon adsorption plate.
The further improvement lies in that: the outer side of the shell is provided with a sound-proof shield.
The further improvement lies in that: the joints of the air inlet cover and the air outlet cover and the shell are provided with sealing rings.
The invention has the beneficial effects that: the air is subjected to three times of silencing treatment by arranging the air inlet cover, the silencing layer and the air outlet cover, silencing plates are arranged in the air inlet cover, the silencing layer and the air outlet cover, the air flows along the silencing plates, and the silencing plates are provided with baffle plates, so that the air flowing speed is reduced, and the emission of noise is effectively reduced; through setting up first filter layer and second filter layer, all be equipped with activated carbon adsorption plate and cross the filter core in first filter layer and the second filter layer, carry out both sides adsorption filtration to the air and handle, improved filtration's effect.
