The Suttner St-164 is a fully stainless steel dual Chemical injector. Able to be installed by anyone with a few tools and extremely operator friendly. The Injector of choice for any wash bay looking to use Stars+Stripes, our 2 step touchless wash and the only dual injector that works in conjunction with our Chem-X Foam Lance. It's as tough as they come and will hold up running chemicals through it all day.
Dosing nozzles control the soap's draw rate. The nozzles have a pin sized hole the soap is drawn though. The size of this hole determines your soap to water ratio. Injector arrives with the correct tips already installed. Dilution range from 10:1 to 200:1.
Both styles come with 10' of pick tube that can be cut to any length.
SAFE FLOW LIDS provide safe and convenient dispensing of chemicals from 1 gallon containers. The threaded lid keeps out contaminants, prevents chemical splashing and spillage. These unique, heavy-duty, machined polypropylene lids attach to a chemical pick up tube with a 1/4" hose barb and can be quickly unscrewed and attached to another container or easily removed and stored. Includes a hastelloy strainer and suction assembly to place inside the chemical container.
STANDARD pick up tube with weight & strainer. Compatible with 1 gallon containers, 5 gallon pails & 55 gallon drums.
