Air Curtain Door

Air Curtain Door Design

1,A circle air curtain tube arranged along the door , 40mm spacing Φ1 open pores, total porosity (900 +1800) × 2/40 = 135 pieces of the ejection holes.
2，Air curtain pipe pressure by 0.6-0.8MPa Inlet, Φ8's path without considering the circumstances of any resistance when the downstream pressure is 0.7MPa, V = 3.255 cubic meter/ min

Suppose there are 135 holes, holes specifications for laser level playing Φ0.9-1mm (0.04 Cv flow when the flow rate is 0.38MPa single orifice flow 33L/min), but according to the total flow split flow around each hole flow 12L, assuming holes of 1mm flow 12L/min, the flow rate is 254 m / s, considering the pipe resistance no needed, the flow rate should be 63.5 to 190 m / sec.
