This stainless steel vacuum works at 70 liters per minute with 700 mm Hg of pressure. It uses four castors and weighs 36 kg. The two 2-liter PC jars are secured with a trap filter, a double rotary vane pump and a 10 cm dia vacuum gauge. This operates with a noise rate of just 50 dB and has a mechanical overflow design. This can even work with a 110 V connection if needed but it will require a 220 V AC connection at 380 watts and 50/60 Hz. This is useful in emergency wards, endoscopy clinics and gastroenterology clinics.
