My 7 year old 200mm exhaust blower finally packed it in a few weeks back, time for a replacement.
I picked the pictured 250mm centrifugal blower (or is it a tiny little jet engine?). It's a Spectrum Customline C250L made by Hygrow.
The C250 series 250mm body comes in two flavours. It's available as the C250L (low speed) with a 105 watt motor, ultra quiet but still 40litres/sec. When ducting is fitted to the exhaust, this blower is nearly inaudible from 2 metres away.
The C250H has a massive 480 watt motor, around 350litres/sec (can't find the spec sheet, still looking) but is much noisier. Maintains very high exhaust pressure, especially good for those big barrel-sized carbon filter systems.
Spectrum also sell some nice axial blowers.
The hot-rod red bodies and chrome-plated fan blades are cool, but the high quality finishes also increase durability. With heavy duty NSK cartridge ball bearings, these fans should be able to run continuously for 5 years at minimum with no failures.
These fans are not cheap, but they're carried by a number of sellers. Shop around- prices vary widely. You should be able to get a C250L for under $200.
