The Foredom Dual Speed Range Solid State Table Top Control is engineered for professionals who use both the Foredom Filer and standard rotary handpieces. A toggle switch selects between two operating modes: set to LO, the control restricts motor speed to 1,000–10,000 RPM (400–4,000 SPM), keeping output within the Foredom Filer's allowable speed range. Flipping the toggle to HI permits full rotary handpiece use at regular motor speeds. This control is also well-suited for use with the reciprocating H.50 and H.50C Chisel Handpieces, which have a low recommended operating speed range of 1,000–8,000 RPM. When used with a hammer handpiece, do not exceed 5,000 RPM. Available in a 115V version (C.EMF-1) and a 230V version (C.EMHF-2). The 230V model ships with a North American plug; use a plug adapter to fit your local outlet.
