Rated 5 out of 5 by from Always a quality product and built to last. Have only used it a couple of times so far but if it works as well as all the other ridgid tools I've switched over to , I'm sure I'll have many year's of happy use from my new vacuum. I'm still waiting for ridgid to come out with their job site radio that actually charges batteries, I'm told it should be out after the first of the year....looking forward to that.

Rated 5 out of 5 by from Feel the power I bought this particular Vac for the suction force, planning on using it with some saws and wood working. While playing around with it in the basement I got it within 6 inches of a trash liner that was laying by the work bench when all of a sudden it was gone. It definitely has some great suction which is what I need. The rolling base went together without any problem and it's very quiet.

Rated 3 out of 5 by from Great shop vac for the price My first rigid vac lasted us 5 years, still works but we had to do some minor repairs over the years ( front wheels feel off, handle broke, cord needed replaced). All minor compaired to the performance of the vacuum itself. Decided to get another model of the same because os hugh discounted price.

Pressure

If a airwatts are 0.117354 * (CFM) * (inches water), then do I calculate correctly that this model no. WD1851 will lift water 12.8 inches high?

306 watts * (1/0.117354) * (1/203 CFM) = 12.8 inches of water

I feel like that number is way too low - I'm sure your product lifts water more than 1 foot high! I may have the calculation wrong or the pressure may be specified another way. What do the units of "G/h" mean?

Besides, it seems like an odd coincidence that this is almost exactly the inches for model WD4070 when the WD4070 is rated 5.0 peak HP and the model on this page is rated 6.5 peak HP.

Thank you for the help.

Answer: 
According to our Product Manager, You need to first think of CFM and Inches of water lift in inches as two different and inversely related measurements. To maximize CFM, you need a wide open path with as little resistance as possible to move as much air as possible. To maximize inches of lift (or better recognize or measure) that flow of air needs to be restricted, or blocked. So to assume that our machines generate 203 CFM and 49 inches of lift at the same time is a miss-conception. The calculation you completed was “at 306 air watts and 203 CFM, what are the inches of lift being produced”… and the answer is 12.8. Essentially, you’ve identified the inches of lift at the rated max CFM and Air Watts. For example, if you solved for CFM at max inches (say 49) you get a really small CFM number, somewhere below .2 CFM. This is because at max inches (the hose is blocked) and there is “no” air moving through the hose.

We hope this helps. Have a good week ahead!

Thank you

Answer: 
Thank you, RIDGID! That really helped me understand how the pressure and CFM are related, and the calculation result of 12.8 inches makes sense now. I didn't realize the airwatts equation was NOT referring to "sealed" inches of water. Now I see why using sealed inches for calculating airwatts wouldn't make any sense.

You mentioned 49 inches a couple times. Is that the sealed lift this vacuum is rated for? If not, would you please share the max water lift rating?

Thank you again.

I think they are usable on both models, but you'd still need to double check. Maybe Home Depots site or just call or email Rigid.

Answer: 
Thank you for your interest in RIDGID!

Please confirm the exact model of your vac. The WD16650 model is not designed to hold a filter bag. But the product above is the model number WD1851 which is designed to accommodate a filter bag. If your vac is WD1851, the part number of the filter bag is VF3502.

If you have any further questions or concerns, feel free to call us at 1-800-4-RIDGID (1-800- 474-3443) or you may send your email to [email protected]
