Cleaning and maintenance

Keeping it clean

All our ducting&diffusers are made from high quality and highly resistant materials without natural fibre additives. The material used is specified within the technical description of your order. If the diffuser/ducting is equipped with tyres, arcs or tensioning systems, these fixed components need to be taken out before washing.

Any maintenance must strictly follow the washing label symbols sewn into every section.

How to clean it up:

1. Very dusty diffusers clean first by means of vacuum cleaner (pressurized air, soft brush).

2. Diffusers/ducting made of fabrics: Prihoda Classic (PMS, NMS), Prihoda Premium (PMI, NMI), Prihoda Light (PLS, NLS), Prihoda Recycled (PMSre, NMSre) Prihoda Durable (NMR), Prihoda Hydrophobic (NLW): wash in washing machine with industrial washing detergents (dosing as per supplier recommendation), at 40 °C, we recommend spinning at 400 rpm and intensive rinsing. According to the contamination level cycle of washing can be repeated or a stronger detergent used.

3. Diffusers/ducting made of fabrics: Plastic (NMF), Foil (NLF), Glass (NHE), Translucent (NMT): cannot be washed in a washing machine. Dirt can be usually effectively cleaned by vacuum cleaner, floor cloth or water stream.

4. Add disinfection into the wash if required at the place of installation. The chemicals of the disinfection must not affect the fabric (see the washing symbols), detergents dosing as per supplier’s recommendation.

5. Dry the diffusers well after washing and install. The air passing through the diffuser can be used to dry the fabric.

6. Surface (induction) dirt can be usually removed by a vacuum cleaner directly on the installed diffusers.
