FAQ's - Aeration
Q: What are the advantages to a linear pump?
A: Linear pumps are easy to install and very quiet.
Q: Are rotary vane compressors always louder than linear pumps?
A: Yes, rotary vane compressors are much louder than linear air pumps.
Q: My rotary vane compressor seems to only last a year or two, is this common?
A: Rotary vane compressors are very reliable and should last you quite a few years with proper servicing of the system. Check filters, airline, and diffusers for dirt or obstructions.
Q: Can I replace my vane compressor with the linear pumps?
A: Yes, commonly done and with little difficulty. But some states and local laws require replacement with identical product. (Check your state and local regulations.)
Q: Why are there two models of the FA340?
A: The FA340 are made as replacement models for 2 major brand s of aerators that have 2 different size concrete openings. The FA340 J fits in the 10" concrete opening and the FA340 N fits in the 12" concrete opening. See Illustration.
Q: My breaker keeps blowing with my aerator unit, what is causing this?
A: The most common problem is debris wrapped around the shaft putting a high amperage load on the motor. For this reason it is a must to have the FA340 aerator on a 4-amp breaker or the motor will burn up in high amps situations. Remove unit from tank and lay the shaft on the ground (be careful not to bend shaft), check shaft for debris. Also check rubber vibration dampers on mounting brackets. Worn dampers mean shaft is out of balance and putting undue wear on the motor bearings causing premature replacement of the unit.
