No onboard pump.\u003c\/p\u003e\u003cp\u003eTwister Venturi uses Venturi vacuum technology — your lab's compressed-air supply pulls vacuum through a Venturi nozzle instead of an onboard diaphragm pump. Fewer moving parts, lighter weight (4 kg \/ 8.8 lbs), and the same reliable processing of large amounts thanks to high mixing speed.\u003c\/p\u003e\u003cp\u003eBubble reduction with two vacuum settings (80% or 100%) and a large, highly luminous display for fast parameter entry. Used flexibly for alginate impression materials and every duplicating and model material on the bench. Requires a compressed-air line at 4.5–6 bar (65–87 psi).\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVacuum Build-up: Compressed air (Venturi)\u003c\/li\u003e\n\u003cli\u003eMax Vacuum: -850 mbar (-12.9 psi)\u003c\/li\u003e\n\u003cli\u003eVacuum Reduction: 80–100%\u003c\/li\u003e\n\u003cli\u003eRotational Speed: 100–450 rpm\u003c\/li\u003e\n\u003cli\u003eConnection Pressure: 4.5–6 bar (65–87 psi)\u003c\/li\u003e\n\u003cli\u003eAir Consumption (max): 28 l\/min (0.99 cfm)\u003c\/li\u003e\n\u003cli\u003eBowl Pressure (abs.): 80 mbar\u003c\/li\u003e\n\u003cli\u003eDimensions (wall): 6.0 × 12.6 × 8.3 in\u003c\/li\u003e\n\u003cli\u003eDimensions (stand): 9.0 × 25.2 × 11.6 in\u003c\/li\u003e\n\u003cli\u003eWeight: 8.8 lbs (4.0 kg)\u003c\/li\u003e\n\u003cli\u003eVoltage: 100–240 V\u003c\/li\u003e\n\u003cli\u003eScope of Delivery: +500 ml bowl \u0026amp; paddle\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003e📞 Inquire Us for Pricing\u003c\/strong\u003e\u003c\/p\u003e","brand":"Renfert","offers":[{"title":"Default Title","offer_id":45881940705337,"sku":"NDS-REN-TWS-VEN","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/7914\/3481\/files\/Screenshot2026-05-25104505.png?v=1779673687","url":"https:\/\/shop.thenewdentalsupply.com\/products\/renfert-twister-venturi-compressed-air-vacuum-mixing-unit","provider":"New Dental Supply","version":"1.0","type":"link"}
