At present, wells are mainly divided into drinking water wells (residential water,rural tap water) and irrigation wells (agricultural irrigation, landscaping, etc.) and industrial water wells(water for company and projects, etc.)。


1. Main features of drinking water wells: caliber: 150mm----254mm, depth: 100m-----300m. TEWATT Recommended air compressor pressure range 20 bar - -30 bar, air flow range 20m3/min(700CFM)----35 m3/min(1250CFM), recommended models TWT700D-20T, TWT850D-24T, TWT1170D-25T, TWT1200D-30F, TWT1180D-35F, etc.; Some rural tap water project wells need to drill about 500 meters, the pressure range need is 30 bar, the air flow is more than 60 m3/min(2113), then TEWATT recommends 2 units TWT1200D-30F (34m3/min~30bar) can be combined.


2. Main features of irrigation water wells and industrial water wells: caliber: 200mm----300mm, depth: 300m-----600m, the distribution of such wells is relatively scattered, recommended air compressor pressure range of 24 bar~35 bar, air flow range of more than 30m3/min, recommended models TWT1200D-30F, TWT1180D-35F, more than four hundred meters can be used in parallel form.
