VPP – Variable Pitch Pulley Instrument

GPS to navigate the performance of a fan that is driven by a variable pitch pulley at all operating positions

Commissioner Rule

Tool to corroborate correct duct traversal

FPP – Fixed Pitch Pulley Instrument

GPS to navigate the performance of a fan that is driven by a fixed pitch pulley; doubles as gauge for measuring diameter of a cylinder without straddling the pulley

Custom Flow Hood Funnel

Personalized airflow hood funnel attracts more TAB sales

Hood Frame

Provides the best means of attaching airlock gasket to hood frame for accurately measuring airflow

Variable Hood Cover

Adjusts to fit non-standard diffusers and grills in seconds

Portable Laser Alignment

Aligns fan driven with variable pitch pulleys

It is accurate, repeatable; you simply do more in less time.

Auto Duct Traverse

It doesn’t get any easier than this. We reduced all the engineering formulations involved in duct traversal to a user friendly portable instrument that provides accuracy and repeatability. The auto traverse apparatus aligns and adhere to the surface of the duct for hands free operation. It guides you to location of traverse holes and the coordinates to read airflow with precision.

With the Auto Duct Traverse, special skill is not required to perform a duct traverse accurately.

  • Attaches and align itself to the duct for hands free operation
  • Measures the width of the duct
  • Pinpoints location of traverse holes on the duct
  • Bore prevents drill bit from walking when drilling traverse holes
  • Measures depth of the duct**
  • Keeps probe and the nozzle oriented appropriately in the duct
  • Guides the probe to precise coordinates to measure air velocity
  • On round duct, you take two sets of reading from one hole
  • Stop flow reading at any point and continue without starting over
  • Read airflow changes remotely when adjusting airflow
  • Safety – Read coordinates at eye level
  • For Ducts up to 72” wide and 36” high and round ducts up to 72” in diameter

Commissioner Rule

As we offer the HVAC Industry the Auto Duct Traverse tool to accurately perform duct traversal we recognized that it would only be appropriate to complemented it with a sidekick, the Commissioner rule. The Commissioner Rule gives the average Joe a tool to verify the accuracy of a duct traversal. Features:

  • It is an airflow diagnostic tool
  • It is a ruler
  • Use it to mark up duct traverse holes with pinpoint accuracy
  • Use it to validate accuracy of duct traversal

Auto Duct Traverse

Most efficient and accurate method to measure airflow in ducts

VPP - Variable Pitch Pulley Apparatus

Instrument is our GPS for navigating equipment driven with variable pitch pulley especially for fans associated with airflow. It reduces complex airflow engineering to a simple user friendly instrument.

  • Energy saving
  • Reduce engineering cost
  • Reduce building renovation cost
  • Reduces downtime and maintenance cost
  • Reduces premature equipment failure

FPP - Fixed Pitch Pulley Apparatus

Our FPP is a gauge primarily used like a GPS for fixed pulley. The gauge is portable and unlike other devices does not straddle the object to measure a diameter.

Secondly, when used with our provided chart or mobile app, it is used to navigate airflow of other pulleys. In other words, when you know the airflow with the present pulley you can use our chart to determine the size of a pulley needed to get any other airflow.

No calculation or complex engineering is required.

  • The most practical and accurate tool to measure the diameter of pulleys
  • Reduce Engineering cost
  • Reduce building renovation cost
  • Reduce building construction time

Hood Frame

Provides the best mean of attaching airlock gasket to hood frame for accuracy.

Custom Hood Funnel

Personalize your flow Yea, each time you raise your hood you get noticed Our flowhood covers are convenient and installs in seconds. The hood covers fit standard square and rectangular grills and diffuser up to 24” X 24” as well round and conical diffusers and drills up to 24” in diameter Think Green and the environment before cutting up a cardboard for your hood cover.

  • Personalized - Provides maximum exposure, self-advertising, like a walking billboard
  • Branding - Offers choice of color Fabric - Lightweight and durable material.
  • Washable - Flowhood gets used in contaminated facilities. Protection - Prevents theft.
  • Installs on your flowhood in seconds
  • Changing the sizes of the opening to fit the grilles is as easy as turning the page of a magazine
  • You can form rectangles just like pealing a banana
  • It stores away in the provided pouch
  • It saves time and makes you more money

Flow Hood Cover

Our flowhood covers are convenient and installs in seconds. The hood covers fit standard square and rectangular grills and diffuser up to 24” X 24” as well round and conical diffusers and drills up to 24” in diameter Think Green and the environment before cutting up a cardboard for your hood cover. In our commitment for simplicity our hood cover offers the following features:

Pulley Alignment Apparatus

Our laser alignment instrument is the most effective tool to align systems driven with variable pitch pulley. Our tool recognizes pulley operating positions and compensates for the pulley opening. In other words our instrument aligns the pulleys along the center of the belt. Specifically, our instrument:

Specifically, our instrument:

  • Reduce maintenance cost
  • Reduce premature equipment failure
  • Enhance equipment performance
  • Saves energy
  • Reduce equipment vibration
