Warranties are at the discretion of the manufacturer as to whether the damage is due to misuse or to defect. PGP Tip The most common problem with this and other larger air pumps is premature diaphragm tearing due to excessive back pressure. People don't tend to understand how much air the large sized pumps produce. If an air pump is powering too small of a diffuser or too few outlets, excessive back-pressure can occur. The solution is to add a tee with a ball valve or other "bleeder valve" so that excessive air can be bled off into the atmosphere. Start with the valve completely open and slowly close it until you have the maximum output from your air diffusers without unnecessary back pressure ModelStartup PowerOperating PowerStandard PerformanceConnectionsNoiseWeightDimensions (Inches)ET3030W25W @ 0.14 bar30Lpm (1.06cfm) @ 0.15 bar14mm Slip; 10mm Barb40dB4.0kg8.18L x 5.9W x 7.0HET4055W30W @ 0.14 bar40Lpm (1.41cfm) @ 0.15 bar14mm Slip; 10mm Barb40dB4.3kg8.66L x 6.10W x 7.48HET6085W55W @ 0.14 bar60Lpm (2.12cfm) @ 0.17 bar18mm Slip; 12mm Barb45dB6.0kg7.99L x 6.49W x 6.02HET80105W75W @ 0.14 bar80Lpm (2.83cfm) @ 0.1 bar18mm Slip; 12mm Barb45dB7.0kg8.26L x 7.28W x 6.73HET100125W80W @ 0.14 bar100Lpm (3.53cfm) @ 0.1 bar18mm Slip; 12mm Barb45dB8.5kg9.37L x 7.71W x 6.96HET12090W90W @ 0.14 bar120Lpm (4.24cfm) @ 0.1 bar18mm Slip; 12mm Barb45dB9.5kg10.43L x 8.36W x 7.79HET150150W150W @ 0.14 bar150Lpm (5.3cfm) @ 0.15 bar18mm Slip; 12mm Barb45dB9.0kg10.07L x 7.87W x 8.74HET200220W220W @ 0.14 bar200Lpm (7.06cfm) @ 0.15 bar18mm Slip; 12mm Barb46dB9.0kg10.07L x 7.87W x 8.74H SpecificationsPower CordGrounded 18 Gauge, 5' 3" LongWarranty2 Years
