The Metalfab model DB1S sanitary feeder offers the simplicity of the standard DB1 unit, while satisfying the most stringent sanitary processing requirements necessary for the metering of such critical materials as pharmaceuticals and foodstuffs. All contact surfaces are of 304 or 316 stainless steel and polished to a #4 finish. All welds are continuous and ground smooth to prevent product build-up and adherence. Gasketing is food grade white neoprene and a rear seal with Teflon packing gland is standard. All external carbon steel parts are painted with white epoxy paint.
Extra clearances are provided beneath the unit for ease of cleaning, but should it become necessary, the DB1S can be disassembled for cleaning without the use of tools.
