The Flo-Dynamics TTCF-9B Base Unit High Flow Hydraulic System Flusher will flush and clean transmission coolers and lines or any hydraulic system of contamination, sludge and varnish deposits, and particles from a failed transmission. The TTCF-9B has a flow rate of 8 GPM to clean heavy duty transmission cooling systems requiring high flow rates. Using the same hydraulic fluid as the hydraulic system being flushed and cleaned, select from two preset air injected scrubbing action flush patterns, or perform a manual flush. Check system cleanliness with the reusable 60 micron screen filter. The TTCF-9B has a preset heater that heats to 140°F in 45 minutes. Air injection agitates the system causing a scrubbing action, removing trapped debris and solidified waxy varnish deposits. Easily switch flow direction without removing service hoses during and between flush cycles with the reverser valve. Flush with or without heat with using separately controlled motor/pump and heater switches. PATENT PENDING.
