Heylo DCS-PF 3500 – dust control system

The DCD dust protection door is used to safely seal off the working or dirty area from the white area. The DCD in combination with the air cleaner and hoses results in the dust protection system DCS for negative pressure maintenance or dust extraction. The PowerFilter 3500 is very well suited for large rooms or heavy dust infestation, as two hoses can be connected here. A negative pressure is created by connecting the PowerFilter in the white area to the DCD in the renovation area (black area). The negative pressure prevents the fine dust from spreading further. As soon as the hose is led through the opening directly to the place where the dust originates in the renovation area, a dust extraction function results.

The dust protection system saves time, money and complications and ensures successful jobs and satisfied customers. There is no need for time-consuming subsequent cleaning as with water-based systems. Knock out and dispose of the dust bags and filters used. Caution: If the air is polluted and H14 filters are used, they must be disposed of properly.

Frequently asked questions (FAQs) about dust protection

What is the difference between the white area and the black area?
"Black area" refers to the contaminated (construction site) area. Hazardous substances arising during remediation include asbestos, dusts or mould. "White area" refers to the rooms located outside the contaminated remediation area.

In order to protect the workman and the occupants of the house, the white area is separated from the black area by partitions so that they are not contaminated. Air purifiers are used to ensure occupational safety within the black area. The black/white principle is laid down in corresponding regulations, for example in TRGS 524 (protective measures for activities in contaminated areas) and TRGS 519 (asbestos: demolition, renovation or maintenance work).

How does negative pressure work? Why do I need negative pressure in the work area?
Negative pressure in the work area prevents dust particles from entering adjacent rooms. With negative pressure, the air only flows into the room (work area) from the outside. Fine dust particles that are in the room air of the work area have no chance of getting out of the area.

When do I need a dust control door (DCD), when the dust control wall (HEYWALL)?
The DCD (Dust Control Door) is a door bulkhead that replaces a room door. When in use, the room is separated by a sheet and is easy to walk through. In combination with an air purifier used to maintain negative pressure, the door bulkhead is an effective dust barrier. The hoses of the air purifier are routed through the DCD to the point of dust generation, resulting in extraction at the workplace.

The HEYWALL is a dust barrier that can be used to reduce the size of large rooms or to separate refurbishment areas from others. With easy-to-install telescopic poles, a sheet can be used as a vertical partition to flexibly separate the room. Different construction variants can be realised with the flexible system: L-shape, U-shape, polygon, room divider or airlock. The system can always be reused, supplemented and extended. Special clamps can be used for the contact surfaces on the sides and on the ceiling. Here, too, the dust-tightness increases considerably with the use of an air purifier. If the rooms have been reduced in size with the system, the requirement for the performance of the air purifier (air exchange rate) also decreases.
