KNF's Model UNC800 (formerly PU842) Vacuum Controller gives you complete control of your evaporative process. Select your preset levels with the touch of a button.  It prevents foaming and boiling, and vents instantly when needed.
Unlike other brands, this controller has no metal components in the gas stream, avoiding frequent, expensive off-site repairs. The FFPM valve system is completely accessible from the rear of the unit for a quick on-site cleaning, if necessary, using a screwdriver.

UNC800 Controller Advantages

Reliable, Maintenance-free Operation, Low Cost of Ownership

KNF uses only premium, corrosion-resistant polypropylene and FFPM resin parts in contact with the gas stream - there are no metal (stainless steel) parts in the gas stream to corrode or replace, avoiding expensive factory repairs and reducing your cost of ownership. The UNC800 is designed to be virtually maintenance-free. All wetted components are easily accessed from the outside rear for occasional cleaning, using only 3 screws. Never a need to open the cabinet.

Maintains Accurate Control Throughout Your Process

The UNC800 tough, ceramic vacuum sensor maintains system vacuum precisely (to within ±0.2%) wherever you need it, for the duration of your evaporative process. The 12-bit microprocessor electronics is user-friendly, intuitive, and configurable within minutes.

Get Repeatable, Consistent Results

You are in complete control. Non-volatile memory remembers your vacuum settings  — move between them during each processing step — there’s no more guesswork or shutdown required. The UNC800 helps avoid foaming and boiling. Store up to five settings for routine solvents, daily projects or even for users on different shifts.

Includes Many Features Not Found on other Controllers

Instant purge and vent control. Auto set point selection. Auto short-cycle compensation, and more, all at your fingertips are included in the UNC800. Because we listened to extensive, in-lab focus groups such as users like yourself, it’s easy to use — and it’s priced right, too!

Easy Setup and Cleanup in Minutes

Simply connect the UNC800 barbed tubing ports to the vacuum pump and to the vacuum system using 3/8" ID tubing. Plug your KNF vacuum pump into the rear of the controller and plug the controller into a wall outlet. It's that easy. No outboard valves, wires or bolted connections to contend with. All cleanable parts are easily accessed from the exterior of the cabinet by removing only 3 screws.
