Why Your Current Starter Capacitors Are Holding You Back

High Purchase Price – Average market price is 15‑20 % above OEM‑grade units.
Frequent Failures – Capacitor breakdowns increase downtime by up to 8 hours per incident.
Inconsistent Capacitance – Tolerance drift (+/- 10 %) leads to motor start‑up torque loss.
Long Lead Times – Standard suppliers quote 30‑45 days, hurting project schedules.
Regulatory Gaps – Missing CE, RoHS, or ISO certifications expose you to compliance risk.

If any of these issues sound familiar, you’re likely paying extra for inefficiency rather than value.
