The Brownies 280 and 390 look a lot alike. What are the differences?
The 280 and 390 Direct Drive Third Lungs⢠use different compressors and have differing number of diver set ups. The 280 is a single head compressor system on a 4.5 hp Robin Subaru that can support 2 divers from 70-80 feet or 3 divers to 45 feet (with an Add-A-Diver kit). Its main advantage is that it’s only 48 pounds– about the same weight as a single tank SCUBA rig. If the divers must carry a system over a great distance to get to their entry point, the 280 would be very attractive.Overhaul is anticipated from 500 to 800 hours of operation. The 280 is a good choice for a recreational diver. The more active hookah diver would be well advised to select the F390, a twin head compressor with a 4.5 hp Robin Subaru. The 390 is a double piston system set up for 3 divers to 90 feet and produces enough air for 4 divers to 60 feet (just need an Add-A-Diver kit for the 4th diver). The 390 only weighs 55 pounds and is the workhorse of the Brownies’ line. It is the perfect selection for the diver
