Dentec Safety supplies a complete range of cartridges so you can choose the appropriate protection for your application. Our "Saf-Twist" design quickly attaches to any Dentec Safety half-mask of full face air-purifying respirator facepiece. The offset connector design improves visibility and allows facesheilds or welding helmets to be worn without interference. Interchangeable cartridge/filter configurations allow you to easily and inexpensively re-configure your protection for use in different applications, simplifying inventories. Cartridges are uniquely designed with a space plenum between the filtering material and the inhalation port. Inhaled air is evenly distributed across the filter which lowers breathing resistance and extends cartridge life
