This is the genuine Poolstar run capacitor rated at 25 microfarads (\u00b5F), manufactured in polypropylene film (PPE), and matched specifically to the 1.10 kW single-phase motor in the Freeflo Racer filtration pump. It sits inside the motor housing and maintains the phase shift between the main and auxiliary windings that keeps the motor spinning under load.<\/p>\n
A run capacitor of this type stays energised continuously while the pump is running \u2014 it is not a start-only device. It provides the electrical phase displacement the single-phase motor needs to generate torque throughout the full duty cycle. Without a correctly rated capacitor, the 1.10 kW motor cannot sustain rotation: it will either hum without turning or draw excess current and overheat. The 25\u00b5F value is fixed to this motor’s winding specification \u2014 substituting a different capacitance, even by a few \u00b5F, risks under-torque or thermal failure.<\/p>\n
This capacitor is confirmed for the Poolstar Freeflo Racer filtration pump fitted with the 1.10 kW single-phase motor. Before ordering, verify your pump’s motor plate shows 1.10 kW output \u2014 Freeflo Racer pumps are offered in multiple power ratings, each requiring its own capacitor value. Do not fit this part to a 0.75 kW or 1.50 kW variant.<\/p>\n
The clearest symptom is a motor that hums audibly but fails to turn when the pump is switched on. You may also see nuisance tripping of the circuit breaker, sluggish priming, or the motor starting only after several attempts. A capacitor that has failed partially \u2014 losing capacitance rather than shorting completely \u2014 often allows the motor to start but causes it to run hot and draw higher-than-rated current. If your pump shows any of these behaviours and the impeller, seal, and wiring check out, replace this capacitor before condemning the motor.<\/p>\n
Isolate mains power and discharge the old capacitor before touching any terminals \u2014 a charged PPE run capacitor can hold voltage after shutdown. Remove the motor end cap (typically two to four screws), note the orientation and terminal connections of the existing capacitor, then unclip or unbolt it from its bracket. Fit the new unit in the same position, reconnect the terminals in the original order, and refit the end cap. The capacitor is non-polarised, but the terminal positions on the motor’s wiring loom are fixed \u2014 match wire colours exactly to avoid incorrect winding connections. Total job time is around 15\u201320 minutes with a screwdriver and insulated pliers.<\/p>\n
PPE (polypropylene film) run capacitors are safety-rated components: the dielectric material and the rated voltage ceiling must meet the motor manufacturer’s specification exactly. A genuine Poolstar capacitor carries the correct \u00b5F tolerance and voltage headroom for continuous duty in the Freeflo Racer’s enclosed motor housing. Off-specification capacitors \u2014 often sold without a traceable tolerance rating \u2014 can cause premature motor winding failure that costs far more than the capacitor itself.<\/p>","protected":false},"excerpt":{"rendered":"
