How to Clean Wire Mesh and Plastic Mesh Filters

How to Clean Wire Mesh and Plastic Mesh Filters

Removing dirt particles, grease and other contaminants from wire mesh and plastic mesh filters may prove economical over the long run vs. continually replacing them. Contaminant removal by cavitation action in an ultrasonic cleaner is both faster and more thorough than using brushes, detergents and high pressure water jets that can also damage wire mesh and plastic mesh. Sonic cavitation is also highly effective for cleaning galvanized steel and aluminum commercial range hood filters in restaurant and institutional kitchens.

You’ll have to undertake a cost/benefit study to determine if an ultrasonic cleaning system is viable for your operation. This will primarily entail the cost of the ultrasonic cleaner, which depends on the size of the cleaning tank required to accommodate the size of filters. Other considerations include how fast the filters can be cleaned by ultrasonic cavitation vs. manual scrubbing using detergents and high pressure water sprays. Hint: ultrasonic cleaning is way faster. Floor space devoted to an ultrasonic cleaning system may be less than for a manual operation. Also to be considered is dirty water runoff from hoses vs. easily drained ultrasonic cleaning tanks.

An Ultrasonic Filter Cleaning Operation

We won’t go into much detail on equipment selection except to call your attention to these points:

1.The internal tank dimensions should be sufficient to accommodate the filter(s). Most ultrasonic cleaning is accomplished in baskets with dimensions slightly less than the internal tank dimensions.

2.Calculate the working depth you need to fully immerse filters. This is the distance between the bottom of the cleaning basket and the surface of the cleaning solution, which is usually delineated by a fill line or approximately ¾ of the tank depth.

3.Note that filters can be suspended from overhead supports but should not touch the sides or bottom of the cleaning tank.

4.Features such as sweep for uniform cavitation action, degassing to speed the preparation of fresh cleaning solutions, a heater and a timer add efficiencies to filter cleaning.

With this information you can shop for a cleaner on the iUltrasonic website.

Once you have your equipment you’re ready to clean.

1.Fill the tank with water and add the required amount of ultrasonic cleaning solution concentrate. For filters we recommend elma tec clean A4 universal ultrasonic degreaser diluted to 2 to 5%. This is a demulsifying formulation to remove oils and grease from metal and plastics.

2.Turn on the ultrasound and activate the degas mode if so equipped to mix the solution and drive off trapped air. The degas mode speeds this, otherwise allow the cleaner to run for 15-20 minutes.

3.Set the thermostat to 70°C for metal filters or about 50°C for plastics and the timer to 10 minutes. With experience you’ll determine optimum temperatures and time. Immerse the basket in the solution.

4.At the end of the cycle remove the filters and inspect. If satisfied, rinse them and allow them to dry. Otherwise repeat the cycle.

Oils and greases released by the elma tec clean A4 cleaning action rise to the surface. Skim them off and set aside for proper disposal.

When the cleaning solution loses its effectiveness it should be replaced. Drain the tank and dispose of it, along with the skimmed oils, in a locally approved manner. Clean the tank according to the user manual then replace the solution for the next jobs.
