1. WALL EXHAUST FANS

   October 7, 2019 9:54 am Leave a Comment

   A brewery came to us in need (talk about a role reversal LOL). Their wall exhaust panel fans were very old and broken. As a result, Indventech visited the site and did a free evaluation. Were the fans repairable? Following a close inspection, the bearings and structure were single-use setups. We concluded they were beyond repair. Subsequently, Indventech offered a solution that worked with their existing structure.

   Using the latest fan technology, we provided the customer with a turnkey industrial wall exhaust fan and automatic shutter set up that would represent them well.

   BTW – the Espresso Porter is fantastic!

   

   

2. ROOF OR WALL EXHAUST FAN BELT REPLACEMENT

   June 14, 2019 6:50 am Leave a Comment

   We received a call today about replacement belts, so here’s some quick thoughts (as in NOT EXHAUSTIVE) for roof or wall exhaust fan belt replacement:

   1. 1. 1. Identify belt length and type                                          BUY NOW

      2. Measure center to center on pulleys (aka sheaves)
      3. Measure the outside diameter of each pulley
      4. Measure the width of the pulley gap where the belt enters
      5. Typically the belts are V type, with either an A or B width
         1. If low HP type fans, usually A
         2. If high HP, usually B
      6. Count the number of grooves (usually one or two) – this tells you how many belts are needed.

   2. Buy the replacement belts-LOL (if you want the best set-it-and-forget-it solution, click here to give us some details and we’ll quote you what we use)

   3. Put the new belts on starting on the smallest pulley and rolling on to larger

   4. Check tension by twisting the belt at the center point – proper tension is typically a half turn at the center distance between pulleys (this is not technically spot on but tends to be very close and avoids needing a belt tension measuring device in a pinch – for less critical equipment like this it works fine)

   5. If tension is too tight or too loose, adjust at the motor mount (should have a way to adjust distance) NOTE: If you use our belt solution above you won’t need to do this!

   6. Re-check belt tension after the fan has run for a few weeks as the belts tend to stretch during break-in. NOTE: If you use our belt solution above you won’t need to do this!

   Things to avoid:

   1. Disconnect and lockout the power before you touch anything!
   2. Belt over-tightening – leads to premature bearing and belt failure
   3. Belt under-tightening – leads to loss of power transfer along with a premature belt and pulley failure
   4. Pulley/Sheave misalignment – check 3 planes with a straight edge/string/laser

3. PRESSURE CONTROLLED FAN BLOWER SYSTEM

   April 26, 2018 9:54 am Leave a Comment

   Just wrapped up a fan blower system where the customer needed to create and maintain a constant pressure inside a closed space where there was not 100% seal. We put together a fan blower system package that included the following:

   • inline intake filter
   • duct
   • blower
   • drive
   • sensor
   • pre-wired
   • tubing
   • run test prior to ship verify functionality

   The customer chose to install themselves with the remote technical assistance of Indventech. It was a fun little project that removed many potential concerns. The customer simply receives the blower, connects the electric, and starts using. All the guesswork is removed.

   While Indventech does perform turnkey systems, we also are comfortable doing as much or as little as the customer requires. We sell products. We sell service. It’s up to you how much of each you want to use. Being a rep, dealer, and producer, we consider ourselves one of the best values in industrial ventilation.

5. BIG, HUGE, GIANT, MONSTER CEILING FANS

   April 5, 2018 6:55 am Leave a Comment

   Thanks to the marketing of a donkey’s rear end (aka big ass OR a$$ for us in the know), many people are now familiar with High Volume Low Speed ceiling fans. To reduce your electric bill (ROI is generally less than 3 years), ask the right questions before proceeding. Here’s a quick starter HVLS checklist (not comprehensive – ahem – must account for the experienced ones out there) to get your wheels turning:

   • Is the area you are considering open and generally unobstructed?
   • Which processes could a breeze hurt?
   • What is the temperature of the air you will be moving?
   • Power requirements?
   • How is your lighting situated?
   • Do you have fire sprinklers and will this affect install?
   • Do I need more than one fan?
   • How much air do I really need?

   Hot air is marketed by the manufacturers. The facts are simple. Avoid costly mistakes and work with the company that invented ceiling fans in the 19th century and finally joined our industrial sector. Use a purpose built, sleek, no frills fan with the highest quality components backed by the biggest ceiling fan manufacturer in the world. Hunter.

   Contact us. We get into the details with you, keep it simple, and quote and/or install (we are both dealer and authorized installer). Do this with confidence and avoid the hype.

6. HUNTER INDUSTRIAL HVLS CEILING FANS + DUKE ENERGY REBATE

   February 19, 2018 9:36 am Leave a Comment

   Hey North Carolina and South Carolina! Duke Energy has added a new rebate in their 2018 program for HVLS Ceiling Fans at $1,000/fan for retrofits where they are replacing less-efficient ventilation fans. What a great opportunity to take advantage of the great benefits that Hunter Industrial and Indventech offer through the supply and installation of the most efficient HVLS fan on the market bar none.

   Did you know?

   • Hunter Industrial makes the most efficient fans in the world, which gives you massive performance while using less power. Less power leads to lower operating costs and year-round savings for you. You’ll save more than half of the energy use compared to other HVLS fans and up to 18 times the power of conventional high speed fans.
   • While other manufacturers use re-purposed gearboxes to inefficiently power fans, Hunter Industrial created the world’s first direct drive motor specifically for HVLS fans. This means our motor is the most efficient based on CFM testing.
   • Instead of taking from outdated sources like our competitors, we teamed up with an aerospace engineer on our fan blade profile to maximize the efficiencies of the rotor for our speeds and diameters.
   • While other manufactures carry HVLS fans, our fans are much lighter and operate on less horsepower. Does that mean we are less powerful than our competitors? No, actually quite the opposite, it means we can deliver more CFM while lowering your operating costs.
   • Our 24’ Titan fan produces 325,000 CFM on 1 HP, while a single 48” barrel fan can only produce 17,000 CFM on 1 HP. One 24′ Titan = 18 BARREL FANS!
   • And INDUSTRY BEST WARRANTY (15 YRS)!

7. DUCT INSTALLATION

   October 18, 2017 8:57 am Leave a Comment

   

   “I need more air”. I hear this all the time. When I get to the site and review the issues, many times the cause of not enough air is poor duct design and installation. When we sell you duct, we are concerned about the system performance too. Our experience designing and installing dust collection systems and duct drives this.

   If you are planning to install your own duct, buy your duct from Indventech and use their design expertise to your advantage.

   If you need installation help, Indventech offers duct and system installation too. It really is the best of both worlds.

9. HOW DO I INSTALL MY FAN OR BLOWER?

   May 2, 2017 9:15 am Leave a Comment

   Why is it worth considering questions about how to install your industrial fan or blower? The industrial fan or blower is the heart of your system, providing airflow and pressure required for your system to perform. Although you may have a contractor say “no problem” when asked if they can install your industrial fan or blower, will they perform best practices to avoid potential problems down the road?

   Here are some general questions for your designer, contractor, or supplier when considering how to install fans:

   1 – Foundation: what characteristics does the structural support need to support my equipment?

   2 – What are the major contributors to smooth operation and long life?

   3 – How will duct work, transitions, and accessories be mounted and installed?

   4 – What maintenance considerations should be addressed?

   5 – What safety concerns should be considered?

   While the above list is not comprehensive, it points you in the right direction. An installer aware of critical details required to have a successful installation will ask questions designed to lead in the direction of best practices. While best practice may not be achievable due to unchangeable variables, you should be aware of all possible details as you assess the feasibility of your industrial fan or blower installation project. Based on the answers you are provided, this will help you determine competence and trust going forward in this very important subject.

   Indventech supplies industrial fans, blowers, and appurtenances with a twist – application assistance with fan centric perspective. Tell us your industrial fan or blower goals, and we’ll help you achieve them.

10. ​WHY IS MY FAN NOT PERFORMING ON THE FAN CURVE TABLE?

    April 11, 2017 9:44 am Leave a Comment

    Any fan worth its weight is manufactured in accordance with designs that have been tested and rated to meet certain performance conditions for given speeds. A fan performance curve or table is then developed to give the fan owner guidelines for what air movement to expect at the supplied speed. This fan performance curve or table indicates the expected volume, pressure, and horsepower for the indicated speed.

    So Why is My Fan not Performing?

    So, when you test the fan’s performance, why isn’t it producing a volume, pressure and horsepower consistent with the fan curve or table you’ve been provided? Some possible reasons are as follows:

    • Incorrect fan rotation direction. While this should always be checked at installation, you would be surprised how often it is not. The fan is typically supplied with an arrow indicating correct wheel rotation. If it isn’t, you can easily determine this by looking at the fan from the drive side.
    • There may be a system effect. Fans are tested and rated at fixed conditions when they leave the factory. Duct may have been applied incorrectly (true “system effect” causing non-uniform airflow), devices upstream/downstream may not be accounted for, or perhaps changes to the system have occurred since initial install.
    • The fan wheel and shaft should be inspected to determine –
      • Correct installation
      • Structural integrity
      • Actual RPM

    These are starting points that may lead to answering, “Why is your fan not performing on its curve or table.” If you still have questions – contact Indventech at 888-864-4344 or email us at sales@indventech.com.
