    its my first build, needs tweeking but im very happy with it. any interest in me making one or bio chambers or anything inbox me .

    this drum works automatically via a float switch which activates a power control module which then turns pump and motor on for a set time which i can adjust

    thanks mate. its took some time to finally get it done , seriously considering starting my own filter manufacturing business

    as its my first build their is a few things wrong which can easily be rectified but I know for future builds.

    I can make any drum/combo units ie with bio's made to order and fully customised to anyones requirements/unique set ups . and everything is made from stainless steel 304/316 grade rite down to nuts and bolts

    sounds like a can of worms being opened in terms of CE marking and testing to prove your not going to fry the new owner etc

    All electronic components used will be CE marked conformed and once a full system is built will be PAT tested by qualified electricians and labelled as such.
    New Owners will be required to use an RCD DEVICE

    or purchase without electronics and take responsibility for it yourself by sourcing your own electronics, wiring installing .

    Thanks Freddyboy, I didnt work from any plans then had to rush due to my very expensive bio sieve made from plastic suddenly failed with a cracked bottom on a weld seam, running bead filters, a pre filters is a must.

    I didnt even bother to clean the welds , well didnt have the time needed it in running asap , needed a bit of tweeking with setting up getting the drum automatically clean at the right time via float switch and installed timer/trigger/delay control module which controls both motor and pump .

    drum motor is an industrial Paralux 62NM Torque 8rpm reduction gearbox running at 24v dc
    pressure pump is a hozelock ultra pump at 3.5bar pressure at 230v ac
    drum screen is 316l 50 micron
    drum size is 480mm x 370mm dia
    overall total size of drum filter inc outlets is 700mm x 500mm x 550mm H
    flow rate 35000 litres comfortably

    professional synergy drum filters made of plastic cost around £2400 new
    I can make mine from stainless steel 316l for less than half the price and for this price I can install the inlet/outlets where best suits the customers layout to allow as easy install as possible .

    I have potential buyers one wants it painted on the outside in black and have it installed by me and willing to pay extra for me doing so, as he's not far from me I dont mind doing this.
    he viewed mine yesterday and said its mint seen it all working by itself. as he actually came for my sturgeon and on the just by chance we got on to subject of drum filters and how he's looking to buy one new

    I can make any size drum or combo units for any pond ie hobbyist 1000 gallon pond rite through to lakes though the latter would need a premises with space lol

    thanks for the message

    after sales care/returns/spares and 1 year guarantee as standard.
    I used to run a ebay business in the past so up to date on customer rights it failed because I couldn't compete on price

    im only building/making to order with a 3 - 4 week turn around time items can be collected or couriered at extra cost.

    I dont have the funds to make them and hope they sell.

    kind regards

    if any one is interested inbox me your requirements, of example i can manufacture a very similar system such as this below for approx half the price and not made from plastic.
    https://kitsukoi.co.uk/collections/s...25-drum-filter

    or these bio chambers I can do them for same price but made from stainless steel . and you can choose your own inlets/outs
    https://kitsukoi.co.uk/collections/s...o-chamber-mini

    these are just examples of what I can do , happy to take deposits or payments up front . visits welcomed to my home address so you can see my drum filter.

    kind regards

    I laughed when I saw the rotation speed of the drum in the following video - I can't remember seeing any drum rotate faster than this, and I'm fairly sure it's not that fast as standard:

    Nice job on your DIY RDF, by the way, although I'd encourage you to use it for a year or more before selling them to other people, just to be sure it performs without undue wear & tear (motor, drum seal, pump, control electrics, etc.). As I'm sure you're aware, a surprising chunk of the cost of many commercial RDFs is the control electronics, so that's one area your simpler design can save a few hundred quid, but it carries a burden of responsibility - one needs to thoroughly test that the control of an RDF is truly reliable, longterm, or customers run the risk of losing a larger investment in the fish themselves.
