Metal clearvue vs Oneida 5hp

[Mitch schiffer]

I couldn't find much on this. I'm am planing on upgrading my dust collector in the next year or so. I have pretty much narrowed it down to the metal version of the clearvue or one of the 2 5hp options from Oneida. What im wondering is which will do better. My main concern is suction I will have some runs that are close to 70ft long. I see the Oneida has a high vacuum option. Is this option better or should I be looking are cfm? The cfm between these is hard for me to understand since they are all have a seemingly different pressure rating.

Mitch, I think the high vacuum version is for CNC

[Malcolm McLeod]

Can't help with comparisons, but I have the EF-5 (assume that's your Metal Clearvue) thru ~30ft of 6" and it will suck the chrome off a ... uhm, never mind. It works good!

The "high vacuum" verison of the Oneida is a smart system that adapts to changing static pressure that comes from applications that may have smaller ports and other demands. CNC, as mentioned is one of those applications.

I got a VFD to run my 5hp/3ph DC, mostly to mitigate the inrush current, but most VFDs these days also include a internal PID loop as standard. If I ever need to connect small tool ports, it is easy to setup the VFD for PID control - using the motor amps as the (input) process variable and the motor speed as the control variable (output). The setpoint for this is the FLA of the motor. Just set the max allowed speed to ~80-90Hz, and if only a small port is connected, air flow is starved, the motor amps drop, and the PID controller will increase the speed ('over-speed', up to the max allowed) to get the amps back to FLA (::rated Hp of the motor). If you throw a 6" port open, VFD controller will slow the motor - again to keep the amps at motor's FLA.

Roll-your-own 'Smart' DC.

My understanding at least from the website the Oneida dust gorrlia has the smart boost feature as they call it. It doesn't appear the high vacuum has this feature. I'm not sure if this is a option for the clearvue.

The high vacuum is designed to perform better over a wider SP range. It does include the smart boost feature, too. From the Oneida site:

Our High-Vacuum systems are designed specifically for use in CNC applications where high amounts of static pressure are needed at the cutter head to adequately collect airborne dust. The unique configuration of our High-Vacuum systems make full use of the high-efficiency U.S. motor and cyclone separator to deliver maximum static pressure to multiple dust ports simultaneously. Combine that with our patented Smart Boost® Technology and you have a dust collector that can deliver twice the airflow using the same horsepower motor!

Good to know since I don't have a cnc I think that will be out of the running. I didn't look into this model as much as it was lower on the list. Thanks for the info.

I'll be seriously considering one of the 5hp units for my new shop building once I have it. I could easily go with a 3hp but might just kick things up a notch, depending on available funding. I had a 2hp predecessor to the original Gorilla in the old shop and it kept up with things pretty well when using one machine anywhere in the shop, but once I had the CNC and was using other machines simultaneously while babysitting the CNC, the performance obviously wasn't as good.

I'd go for it. I'm very happy with my 5HP Oneida. Really no complaints about it at all. But don't have a CNC, FWIW.

Unless I decide to do something 'Very different" and buy the Harvey in combination with a little different shop arrangement, it will be one of the Oneida systems, either 3 hp or 5hp.

[Mitch schiffer]

I was considering the harvey but I ordered a harvey bandsaw months ago. I'm still waiting on the bandsaw and get no response from email, Facebook, or phone calls on the estimated shipping date. It was originally going to be shipped late December. This has made me a little leary of the harvey.

I would not buy a single phase dust extractor for a bet, it is an archaic and limited idea and should be done away with seeing we have cheap VFD's now available. I run my CV 1800 at 70hz and it rocks, has soft start and low current start requirements and if I choose to I can slow it down if needed. In Oz every CV I have sold or know of except for two is run by a VFD and adding remote control is a simple 5 minute exercise. Want to run an automatic blast gate system? then a VFD is your friend.

As for 90hz, would a normal three phase motor be happy at that speed? I limit to 70 hz after chatting to Bill Pentz and seeing two episodes of solid objects getting into the impeller housing and the damage caused. One only needed the wrapper around the impeller repaired and one had severe impeller damage and it was this possibility that caused BP to caution about going above 70hz. Another thing I think will be pertinent to impeller speed is what speed does the impeller efficiency fall off at.

The CV Max was invented to achieve at 50hz in countries outside the US the same airflow as the 1800 achieved at 60hz. That was pre VFD days and today the need might be re-assessed. It only became feasible to sell the CV in Oz because affordable VFD's became available but it took Oneida to recognise the advantages VFD's gave to dust extraction operation.

While I do think this could be a interesting project, I know that projects sit around in my shop for quite a while. Running the ductwork will be enough of a project to take on since right now I have a mobile unit I wheel around. I would prefer to just buy a plug and play unit for these reasons. If I had the time and found a decent used cyclone I would definitely consider a project like this. I did miss out on a 3 phase cyclone that sold at a auction near me for a measly 6$! That would have been a good candidate unfortunately I didn't see it in time.

This is the model I am considering. Is there any reason you chose this in particular comparedto other brands? Did you look at the Oneida at all when you were shopping around?
