Cleaning

In order for your filter systems to work properly, they must be cleaned regularly. Cleaning by indusa is the easiest solution for you and cleaning by us always includes a visual inspection of the plant. The following components of the filter system must be cleaned at regular intervals:

  • Housing from inside and outside
  • Pre- and post-filter (metal mesh)
  • Main filter inserts
  • electrostatic filter systems - ioniser and collector
  • mechanical filter systems - main filter inserts F9, H14 (cannot be cleaned)
  • Dust filter systems - cartridge filters or pocket filters (cannot be cleaned)

The cleaning can be carried out in three different ways:

  1. Cleaning on site at the customer
  2. Cleaning with on-site replacement
  3. Cleaning at the indusa i-center

1. cleaning on site at the customer

The cleaning includes the following services in addition to the removal and installation of the inserts:

For electrostatic filter systems

  • Housing interior: Cleaning and disinfection
  • Pre- and after-filter: cleaning with ultrasound or steam
  • Collector(s): Cleaning with high pressure and/or ultrasonic or steam equipment
  • Ionizer(s): Cleaning with high pressure and/or ultrasonic or steam equipment

For mechanical filter systems

  • Housing interior: Cleaning and disinfection
  • Pre-filter: cleaning with ultrasound or steam
  • Foam pre-filter: cleaning if possible, otherwise replacement
  • Main filter cartridges: cannot be cleaned and must be replaced.

New filter inserts are not included in the scope of cleaning and must be ordered separately in advance of cleaning. Disposal must be carried out by the customer.

The cleaning carried out is documented in the cleaning protocol. The cleaning does not include maintenance of the system, but only a visual inspection. Small repairs (e.g. replacement of spray electrode) can be carried out directly.

2. cleaning with on-site exchange

In an on-site replacement, the soiled inserts are exchanged for inserts from the indusa exchange stock (electrostatic filter systems) or for new filter elements (mechanical filter systems). The exchange inserts correspond in type and type to the exchanged inserts.

Cleaning with on-site replacement includes the following services:

  • Housing interior: Cleaning and disinfection
  • Exchange of all filter elements
  • For electrostatic systems against elements from the indusa exchange pool
  • For mechanical installations against new elements

The cleaning carried out is documented in the cleaning protocol. The cleaning does not include maintenance of the system, but only a visual inspection. Small repairs (e.g. replacing insulators) can be ordered directly.

3. cleaning in the indusa i-center

When cleaning in the indusa i-center, the filter inserts are sent in an indusa transport box on a pallet by the customer and cleaned in a cleaning plant. After cleaning, defective ionizers, collectors or knitted filters will be repaired against separate invoice.


Cleaning at the indusa i-center includes the following services:

  • Shipping of a suitable transport box to the customer
  • Cleaning of the sent in inserts
  • If necessary, repair of the inserts against separate invoice
  • Shipping of the cleaned inserts in disposable packaging on pallets

The dispatch of the soiled inserts in the transport box, on pallets is carried out by the customer at his own expense.
