It’s been a hot, but beautiful summer so far. And at Duff, we’re just getting into our groove. The last of our series of Duff Summer Counter Days is upon us: 
Friday, July 29, is focused on point-of-use (“POU”) water treatment options. In addition to some blowout sales, we’re introducing a couple new products. Just as important, this is your LAST CHANCE TO GET HOT DOGS! In non-hot-dog related news, I encourage you read to the end of this post, where you’ll learn about some of the special discounts we’ll be promoting in connection with this final in the series of Duff Summer Counter Days.
This is a long post, but if you stick with it, the reward is well worth it.
GRO Series High Efficiency RO Membranes
First, Pentair recently released its GRO series of high efficiency reverse osmosis membranes. These RO membranes integrate a 100% dry membrane to help maximize its lifespan and provide enhanced performance to the end user. How enhanced? How about a 50% recovery rate, while maintaining a retrofit-able design for easy integration? How do you like them apples?
Available in 36, 50 and 75 GPD models, the GRO will revolutionize the way your business uses RO! But there’s more:
- Rejection performance comparable to standard RO elements
- High rejection stability at high input TDS
- TLC Thin Layer Composite membrane
- 100% dry membrane maximizing shelf life
For the complete specifications on these RO membranes, click here. For a quick video on the GRO, see below. While I can’t guarantee it will be the most valuable 57 seconds of your life, it does give you a good glimpse at the future of residential ROs. (But keep reading below!)
Trust me on this: The more you learn about these membranes, the more they GRO on you. (Sorry.)
Blowout Prices!
Next, we have surplus inventory of cartridge filters and housings we’re looking to clear out so we can make space for new product.
Harmsco Filters
For one, we have a limited supply of Harmsco 801 Series polyester filter cartridges. These are the class of the industry, with flow rates 4-6 gpm per single (9-3/4″ x 10″) length. They are cleanable and reusable in most applications and micron sizes. Here are some other highlights of the 801 Series filters. 
- Lower overall operating cost
- Longer filter runs for fewer change outs
- Lower initial pressure drops
- Reduced maintenance down time and cost
- Increased contaminant removal
- High flow capability
- Pleated design for more surface area
- Color-coded end caps for easy product identification
- Thermally bonded end caps to ensure better sealing
- Protection of RO System and/or downstream equipment in high-flow applications.
The sale applies to various micron ratings, from 0.35-20.0. The best part of all is the price:
Reg. $31.60 – $8.86 Counter Day Special: $5.99-$10.99
Filter Housings with Mounting Brackets
We’re also offering closeout prices on some clear filter housings that all come with mounting brackets.
- 10” Clear Housing with Stainless Steel Threads: $24.99
- 10” Clear Housing with Valve-in-Head: $24.99
- Big Blue 20” (¾” thread) w/ Pressure Relief Valve: $36.99
Did you know that we offer a complete kit for filtering out lead in the water? This has been our hot seller with school districts lately, as they’re all afraid of becoming the next news story.
That’s why we developed a simple, all-in-one, in-line lead filtering system. In one package, we provide a 2.5″ x 10″ clear filter housing with 3/4″ female ports; a lead cartridge filter with a 0.5 micron rating that also filters out chlorine taste & odor, plus cysts, including 99.5% of cryptosporidium and giardia cysts; a wall bracket; and a wrench to open the filter housings.

If you don’t believe me, just give us a try. The most talented, and best trained, staff in the industry is available, and waiting to hear from you!
DWC RO Series
Before we move on to the most important thing, any discussion on POU water treatment must mention reverse osmosis. We at Duff are lucky because we have an excellent product for you to sell your customer in this product category. Indeed, this has been one of our most popular products since we introduced it about a year ago.
The DWC RO series residential systems come in 50 and 75 gallon per day options; as either “quick change” (with proprietary replacement cartridges) or with standard screw-down sumps; with an optional booster pump for low PSI installations.
These are made in the USA and, as important as anything, they are reliable and easy to install!
Free Hot Dogs! Prizes, Raffles!
Did I mention that we’ll have free hot dogs? We’ll also be giving out prizes all day long. Stay tuned for more info. For now, here is the flyer on this special event. Until then, enjoy this picture of a dancing hot dog . . . .
