A. Blowing The installment of a large-sized filter at the end of inlet is recommended.
1. The total sections of outlets should be half more than the outlet section of the blower.
2. If use as an air pump under water, the water level should between 80% of the maximum which show on the catalogue.
3. At least one meter long iron tube should be applied to the blower when it used as deliver air under pressurization, due to the exhaust temperature will be 10°C higher than the normal atmospheric temperature by the compression of air.
B. 吸風(fēng)-出口可裝消音器。
1 .吸入口之總截面積應(yīng)大于氣環(huán)式真空泵入口截面積之1/2。
2.如用于全閉吸著時或管路特長需長時間工作請先咨詢本公司營業(yè)部。
