The commercial series equipment are careful handmade by our chief engineer. The large size and commercial loading requires careful production methods that differs from the hobbyist range. It took us many years of R&D to make use of the efficient and high air handling needle wheel pump on a commercial scale. Our Q6 uses just 390 watts as compared to our competitors similar size skimmer which uses 1000 watts to power its pumps. This equates to a saving of 5344 kilowatts(Approx SGD$1400 in Singapore) a year.
