Fabric air ducts washing

Aggressive environments and frequent washing will shorten the life of the product. The manufacturer has no requirements for the use of this product. Washing of textile air ducts can be done manually or in a washing machine according to the instructions below:

  • Washing should be made using gentle detergents or disinfectants at a temperature not more 45 ° C during 15 minutes.
  • Drying has to be at the room temperature, depending on the type of fabric, is no more than 3-4 hours.

If you have an industrial washing machine, you can wash the fabric ducts by yourself, keeping the conditions determined after consulting the manufacturer of the detergents, after laboratory studies and tests on dirty textile ducts.

How to maintenance for fabric air ducts

Below is an example of technical instructions and recommendations for the maintenance of a textile duct.

Preparation of textile air ducts for disinfection

Proper preparation of fabric air ducts for washing and disinfection includes 2 stages:

  • Separate the sections and spray nozzles, then combine these elements according to the capacity of the machine.
  • Turn the sections inside out and remove any dust that may be there.

Washing process for the fabric air ducts

Load factor: This is the ratio between the amount of linen (kg) that the washing machine can wash and the capacity of the tumble dryer (liter). Be careful, drum capacity is not equivalent to machine power (weight). Basically, loading takes place in the proportion of 1/18.

Rinse ratio: This is the ratio between the number of kilograms of linen washed and the amount of water in the machine. The middle level is 1/5, the high level is 1/7.

Example: if the theoretical machine capacity is 16 kg and the water volume is 80 liters for the pre-wash, and 60 liters for the final wash, you can wash in a ratio of 80/5 or 60/5 kg of linen, or 16 and 12 kg of linen, respectively.

* 15 g / kg for medium hard water, 25 g / kg for hard water.

** 40 ° C for frequent washing, otherwise 60 ° C.

*** In case of heavy contamination and only for white textiles: it is possible to carry out additional treatment with OZONIT (disinfectant and bleaching agent). After the first rinse, start a disinfectant cycle (8-10 g / kg of agent at 48 ° C bleach) for 8 minutes with a rinsing factor of 1/5, followed by rinsing in cold water. Then, during the second rinse, add 40% bisulfite (5 cm3 / kg of linen) in order to neutralize the bleach.

**** It is desirable to have a bacteriostatic protection function.

Drying fabric ducts after washing

  • Light spin can be used at the end of the rinse cycle
  • It is preferable to dry in the open air or in an industrial dryer if it is equipped with a thermostat that allows you to limit the drying air temperature to 45 ° C maximum
  • Drying at room temperature, depending on the type of fabric, is no more than 3-4 hours.
  • Never store wet sections

Cleaning tips for the fabric ducts

  • Regular cleaning of the ducts preserves the air and climatic efficiency of your equipment.
  • It is very important to check the cleanliness of the textile air ducts regularly , especially in the first months of use, in order to determine the number of washes.
  • Sometimes fabric ducts are equipped with tapered meshes located inside the duct: after connection, at the beginning of the duct or after a bend.

Cone screens are especially prone to contamination because they provide filtration and prevent the textile duct from getting dirty. In this regard, it is very important to monitor their condition periodically and clean them with a high degree of contamination. Disassembly is easy as they are secured with zippers

The cost of washing fabric air ducts

TEXAIR does not provide a quick wash and disinfection service for the textile production duct. Such an air duct must be sent at your own expense to a specialized organization. The price of cleaning depends on the size of the fabric duct and the degree of pollution.
