Customer Reviews for VEVOR Cyclone Dust Separator, 4" Retrofit Cyclone Separator for Dust Collectors, ABS Dust Deputy With 2" Hole O.D. Connector & Hose for Wet/Dry Shop Vacuums, Fits 18.9-37.85L Tank (Tank Exclude)

Good Quality

This is a large size cyclone with 100 mm in and out ports. It comes with 50 mm reducers and a short lenght of 50 mm vinyl hose, screws and fitting, attach to a container and you are ready to go. The plastic material seems very solid, it could be some kind of Polycarbonate, which is an excellent plastic very very strong and tough. The hose is of lesser quality, imo it is too soft and retracts when under strong pressure, the inside is not smooth, and so not optimal, there are better suited hoses on the marked that are quite inexpensive, I use a blue hose, which is very strong and smooth inside, it sells for 6-15 €/m depending on dimensions, it is excellent, keep your hoses short. Use a powerful large volume suction machine to get the full benefit of this cyclone. Combine your DIY system with a HEPA 14 filter, and you could save several thousands of Euro. Vevor should offer a complete kit, the cyclone alone is only a small piece in a larger system. As always Vevor has a solid delivery system and an attentive service system, should something go wrong.

Works fine. Adapter was useless for my design. Basic cyclone was worth not having to build another Thein separator. My previously built Thein separators have worked better. Time will tell if this brittle plastic cyclone was worth it.

I’m a huge fan of low profile separators, so when I started shopping, I looked at recent patents in the US PTO to see what I could learn about current and emerging technologies. I saw one in there by a guy named Thomas Huntley that looks exactly like this one, although yours spins the other direction. I’m not sure if that absolves you from infringement, but it was encouraging because I know so much of what he has invented works exceptionally well. So I bought it. And it does work exceptionally well and at a really cheap price. I’ll let Tom know so he’s on the lookout.

Unfortunately did not receive the cyclone as the courier did not provide notice of arrival before returning back to the supplier. Still want it but need to work out the delivery issue

It does its job as it should however the sizing is not quite right. It’s more like 3-3/4” I had to wrap duct tape around the inlet and outlet to get it to the correct dimension for 4” hose. supplied reducers also don’t fit correctly if you plan on using them, plan on modifications to make them stay in place. 3 star mainly for lack of support when contacting customer service.
