C.A.P. is no longer in business, we recommend going with an alternative, comparable replacement controller such as the Titan Controls Apollo 3. The NFT-1e and NFT-2e fixed cycle timers by Custom Automated Products are the simplest devices available for turning a device ON and OFF at precise intervals. They are great for turning on and off pumps in aeroponic and nutrient film technology systems. The NFT-1e timer is pre-set to turn ON for 1 minute and OFF for 4 minutes. The NFT-2e timer is preset at 3 minutes ON and 5 minutes OFF. NFT timers are rated for 15 amps @ 120 volts. 5 year warranty. This unit is refurbished by the original CAP factory who produces the products. It carries the same 5 year warranty as the new unit.
