Flo-Dynamics
Flo-Dynamics supplies fluid service machines here: ATF exchangers and coolant service machines. Seven machines are listed, all new equipment under Shop Equipment. The model number and the description in each title are what we publish. Anything beyond that comes from the manufacturer’s own spec sheet for the exact model.
What we stock
Four machines sit in Transmission Fluid Exchangers. The TS410 is an ATF inline exchanger and is the lowest priced of the four. The PROMAX40 is a heavy duty ATF inline exchanger. The TSD450LCD is an ATF inline and dipstick exchanger with chemical injection. The TSD650LCD, listed as Flo Dynamics without the hyphen, is an ATF inline and dipstick exchanger and is the highest priced Flo-Dynamics machine on the site. The split to settle first is whether you need dipstick service as well as inline service; the TSD models cover both, the TS410 and PROMAX40 are inline.
Three machines sit in Coolant Exchangers. The C-VAC3 is a drain and fill plus inline flush coolant service machine. The VacFill3 and the VacFill3+ are vacuum and fill coolant service machines, with the VacFill3+ the higher priced of the two. Again the method is the deciding factor: drain, fill and flush on the C-VAC3, vacuum fill on the VacFill units.
Buying and support
We do not publish tank capacities, adapter lists, hose sets, cycle times or electrical requirements for these machines, and you should not assume two models in the same family match. If a fitting or a capacity decides the purchase for you, call before ordering and we will check the listing and the manufacturer’s data with you.
All Flo-Dynamics items here are new machines and carry the manufacturer’s warranty. The 7-year / 1,000,000-mile extended warranty offered on qualifying remanufactured drivetrain units does not apply to shop equipment, and there is no core charge on new equipment. We ship by freight, so plan for a delivery point a freight truck can reach and a way to unload. Payment is by bank transfer or check. Call 216-250-6666 or email sales@varietyengines.com to confirm a model, ask what ships with it, or arrange freight.
