Connections
Most models come with two connection options.
The ET30 and ET40each have a plain horizontal 14.0mm (0.55") O.D. outlet connection fits tight on a 1/2" I.D. tubing or loosly with a 5/8" tubing. A rubber elbow is also included. Each pump also comes with barbed fitting that threads into the threaded interior of outlet to provide a 10.0mm (0.39") O.D. barb which fits well in 3/8" I.D. tubing.

The ET60, ET80, ET100 and ET120 each have a plain horizontal 18.0mm (0.71") O.D. outlet connection fits very tightly on 5/8" I.D. tubing or loosly in 3/4" I.D. tubing. A 3/4" rubber elbow is also included. Each pump also comes with barbed fitting that threads into the threaded interior of outlet to provide a 12.0mm (0.47") O.D. barb which fits well in 1/2" I.D. tubing. The ET50 and ET200each have only a plain horizontal 18.0mm (0.71") O.D. outlet connection fits 3/4" I.D. tubing. A 3/4" rubber elbow is also included.

On all models where the "brass" is used to connect to a septic pump alarm, the brass is 4mm or about 1/32nd.2 Year Warranty
This warranty does not include the diaphragm kits, which are a replaceable, wearable part (typically replaced every 12-18 months). 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 (Inches)ET3030W25W@ 0.14 bar30Lpm (1.06cfm) @0.15 bar14mm Slip; 10mmBarb40dB4.0kg8.18L x 5.9W x 7.0HET4055W30W @ 0.14 bar40Lpm (1.41cfm) @ 0.15 bar14mm Slip; 10mmBarb40dB4.3kg8.66L x 6.10W x 7.48HET6085W55W @ 0.14 bar60Lpm (2.12cfm) @ 0.17bar18mm Slip; 12mm Barb45dB6.0kg7.99L x 6.49W x 6.02HET80105W75W @ 0.14 bar80Lpm (2.83cfm) @0.1bar18mm Slip; 12mm Barb45dB7.0kg8.26L x 7.28W x 6.73HET100125W80W @ 0.14 bar100Lpm (3.53cfm) @0.1bar18mm Slip; 12mm Barb45dB8.5kg9.37L x 7.71W x 6.96HET12090W90W @ 0.14 bar120Lpm (4.24cfm) @0.1bar18mm 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 8.74HSpecificationsPower CordGrounded 18 Gauge, 5' 3" LongWarranty2 Years
