AFM40 Dual Cleanroom Fogger- Dual 80mm Fog Outlet

Description

AFM40 Dual Cleanroom Fogger with two 80mm fog outlets for Airflow Visualization Tests

AFM40 Dual Cleanroom Fogger  is used in smoke studies and airflow visualization tests. It produces a pure white fog with 8-10 micron fog droplets at about 2.0 cubic meters of pure fog per minute, which is directed out of TWO 80mm fog outlets. You can order 80mm hoses, 50mm hoses, 80mm fog wands and 50mm fog rakes. This smoke machine is designed in a 316L stainless-steel enclosure with two 80mm Fog Outlets, two Carry Handles, and an 13.5 Liter Water fill. The AFM40 Cleanroom Fogger provides adjustable fog volume and adjustable fog velocity through the touch pad control, and also offers an optional wireless remote control of fog volume and fog velocity. Visualize airflow in a large Barrier Isolator and Bio-Safety Cabinet, BSC, or operate the AFM40 Dual from a distance using wireless remote control. Use touch pad controls for fog velocity and fog volume or optional Wireless Remote Key FOB.

Smoke study foggers are also referred to as cleanroom foggers, smoke machines and smoke generators. The AFM 40 Dual is used in smoke studies and airflow visualization studies to visualize airflow uniformity, airflow turbulence in small clean rooms and around equipment and at door entry in hall ways. Metrology Managers in Pharmaceutical ISO suites are driven by FDA and USP guidelines to verify airflow performance. We provide both ultrasonic foggers using water only, Below is a selection of smoke generators and performance details for each smoke machine, which you can match to your requirements for your smoke studies in clean rooms, BSC, ISO suites and barrier isolators.

Why does the AFM40 use Touchpad Controls, instead of Touchscreen Controls?

Touchpad Controls on a product are superb in high humidity airflow environments, which makes a Touchpad Control especially valuable when used on a water based, cleanroom fogger used in high water condensation environments. The Touchpad is a single, water tight interface, that does not allow moisture to contact the electrical switches under the control surface. A Touchpad is used on the AFM40 Cleanroom Fogger to control fog velocity, fog volume and mode of operation. The touchpad prevents water condensation, which naturally builds up on the fogger surface during a smoke study, from leaking in and around the touchpad controls. It allows the fogger display to be viewed without concern of electrical mishap. The entire front control surface of the AFM40 is one pad with touchpad control of all AFM40 functions, keeping water condensation and moisture away from the internal AFM40 electronics. A secondary advantage to using a touchpad control is that a wireless remote receiving antenna can be integrated underneath the touchpad, allowing control of the AFM40 using a Wireless Remote FOB from a typical distance of 20+ feet. This feature allows the wireless receiver to be completely isolated from any humidity or water condensation during the smoke study, which is a common problem to a top mounted, wireless receiver used in various instruments for remote operation.

Touchscreens are colorful and digitally controlled; but touchscreens have two primary parts, an outer plastic bezel and the touchscreen itself, which is designed with a glass surface and underlying electronics. Many phones and tablets use a capacitive touchscreen. Under the glass surface is a transparent grid of conductive material carrying a tiny electrical charge. Your body also conducts electricity, so when your finger touches the glass surface of a touchscreen, it makes a slight change to the electrical field at that touchscreen location, which controls a function in the instrument. The Touchscreen is installed into physical opening of a fogger enclosure, and the bezel hides the metal hole and allows the touchscreen to look as if the touchscreen is integrated onto the metal surface.

Since the bezel is not actually part of the touchscreen, water condensation and water humidity could migrate under the bezel edges, since the edges are not water tight, possibly allowing water contact with internal circuitry of the electronic PC board under the touchscreen. Phones and tablets are not normally used in water condensation applications, so communication devices do not have the same water leaking concerns as a touchscreen on a cleanroom fogger. A touchscreen is based on a capacitive electrical transfer from the finger to the screen surface; and if too much humidity is on the screen surface when touching one touchscreen button, the humidity may also simultaneously activate a second touchscreen button in close proximity of the surface that was touched, causing false touches, missed touches or erratic input into the controls of the touchscreen, possibly causing the fogger to operate incorrectly. A capacitive touchscreen can also interpret water droplets or a water film as electrical changes similar to a finger contact. Lastly, touchscreens have a glass surface, which can be broken if any mechanical tools accidently strike the surface of the glass screen. For this reason, our AFM Cleanroom Foggers and our Apollo LN2 Foggers do not use Touchscreen Controls to control fog velocity, fog volume and Wireless Remote Control; but use TOUCHPad Controls for more reliable, long term operation of our Cleanroom and LN2 Foggers in your smoke studies airflow visualization tests.
