One press of the foot pedal flushes the bag with nitrogen or another inert gas of your choice, retracts the stainless steel nozzle, and impulse-seals a 1\/4\" wide bead across the full 50\" bar. Total cycle takes a few seconds and produces a leak-proof, oxygen-free package every time.\u003c\/p\u003e\u003ch3\u003eGas Flush with Venturi Vacuum, No Oil or Maintenance\u003c\/h3\u003e\u003cp\u003eAir pressure from your shop compressor drives a 100% maintenance-free venturi vacuum pump. Because there are no electric motors, oil reservoirs, or wear parts in the vacuum path, the AVN-50 runs without the noise, vibration, heat, or particulate that comes off conventional rotary-vane pumps. Vacuum flow is 6 CFM and max vacuum pressure is 27 inHg, which is enough to fully evacuate clear, foil (Mylar), mil-spec, and ESD bags. The gas flush and vacuum functions can each be switched off, so the same machine doubles as a plain impulse sealer when a vacuum or inert atmosphere isn't needed.\u003c\/p\u003e\u003ch3\u003eRetractable Stainless Steel Nozzle with Safety Interlock\u003c\/h3\u003e\u003cp\u003eThe nozzle is automatically retracted before the seal bar fires, so it never gets pinched and never leaves a witness mark in the seal. The AVN-50 will not fire an impulse until the upper and lower jaws fully meet. That protects fingers near the bar and guarantees the heating element only energizes against a properly closed bag, so you don't get partial or wrinkled seals from an early pedal press.\u003c\/p\u003e\u003ch3\u003eClean-Room Compatible Chassis\u003c\/h3\u003e\u003cp\u003eThe frame is rust-treated, powder-coated steel; the pressure bar is powder-coated aluminum; the foot switch is encased in steel. None of that is cosmetic. Powder coat survives the chemical wipes and washdowns required in medical device packaging and electronics assembly, and the chassis is rated clean-room compatible out of the box.\u003c\/p\u003e\u003ch3\u003eDual Nozzles and Low-Pressure Bar Close Standard\u003c\/h3\u003e\u003cp\u003eThe AVN-50 ships with dual nozzles and low-pressure bar closure standard. Two stainless steel nozzles draw vacuum from opposite ends of long bags simultaneously, cutting cycle time on 50\" production runs in half compared to a single-nozzle arrangement. The low-pressure bar close softens the initial jaw contact so thin or pre-formed bags don't blow out their gussets when the bar comes down. Both features come standard on the AVN-50 and only the AVN-50 in the series.\u003c\/p\u003e\u003ch3\u003eConfigurable for Stricter Environments\u003c\/h3\u003e\u003cp\u003eFor facilities that need more than the standard configuration, the AVN-50 can be ordered with a bi-active seal (top and bottom heating for thicker or laminate bags), full stainless steel construction, CE certification, a vacuum filter, a vacuum regulator, 220V operation, and a digital temperature controller. These are factory-fitted options chosen when you place the order, not field retrofits.\u003c\/p\u003e","brand":"Sealer Sales","offers":[{"title":"Default Title","offer_id":51310903525661,"sku":"AVN-50","price":7995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0699\/4716\/2909\/files\/57341_AVN-50-img-1.jpg?v=1780307089","url":"https:\/\/thechefstore.com\/products\/sealer-sales-avn-50-50-retractable-nozzle-vacuum-sealer-with-gas-flush-1-4-seal-width-27-inhg-vacuum-foot-pedal-operation","provider":"TheChefStore.Com","version":"1.0","type":"link"}
