Where should the water go?
Wet the brush, wet the ground — or cover both working zones.
A rotating brush can lift fine dry material into the air. Water helps the fines cling together and remain with the material being swept. The important difference is when and where that moisture reaches the dust.
Apply water to the brush
Nozzles direct water onto the bristles or into the brush’s working zone. Moisture is carried into the material as the roller meets it, helping bind fines at the point of agitation.
- Why choose it? Target water where the brush is creating dust, especially within a contained roller-and-collector setup.
- Useful where: The main roller is the dust source and you want controlled, local application rather than wetting a wider area.
- What to check: Coverage across the brush width. One wet patch does little for dry material at the opposite end.
Its limit: Wetting the main brush does not necessarily damp the ground before the first contact, or control dust raised by a separate side brush or vehicle tyres.
Apply water to the ground ahead
A forward-directed spray wets the dusty deposit before the bristles disturb it. The brush then meets dampened material, rather than relying on moisture transferring from its bristles.
- Why choose it? Dampen a dry layer before the first sweeping contact, including an exposed working area outside the main roller housing.
- Useful where: Loose fines cover an open hard surface or a kerb line needs damping before a gully brush draws material in.
- What to check: The wetted strip must overlap the actual brush path, including when the sweeper is angled.
Its limit: A spray that lands behind the brush is too late for that first contact. Wind and nozzle position can also leave part of the working strip dry.
Why not just spray the visible cloud? Water is more useful before or at the point where dust is disturbed. Trying to catch already airborne fines with a general sweeping spray is less dependable than damping the deposit or brush working zone first.
Using a gully brush? Ask whether a separate nozzle is needed ahead of it. A rail serving the main roller may not reach the side brush’s sweep. Where both zones generate dust, discuss coverage for both rather than assuming a larger tank solves the problem.
Nozzle layout matters
Specify the spray pattern with the collector fitted.
The guard, collector and brush housing change where nozzles can sit and where the water can reach. A suitable installation must put moisture into the working material without the spray being blocked by another component.
Identify the dust source
Look at whether dust starts at the main roller, a side brush or before sweeping as tyres cross the deposit. That determines which area needs damping.
Check the complete layout
Confirm nozzle brackets, rail width, collector clearance and coverage at the working angle. Kersten’s pedestrian instructions illustrate different nozzle mounting positions with and without a collector.
Confirm the supplied arrangement
Ask whether your quoted kit wets the brush, sprays the ground or uses separate nozzles for both. The tank size and mounting position alone do not answer that question.
Capacity, weight and refill access
More litres mean more working water — and more load.
| Capacity | Useful starting point | Water weight when full | Important consideration |
|---|---|---|---|
| 5 litres | Compatible pedestrian work over smaller areas with nearby refilling. | Approximately 5 kg | Check the power-unit and nozzle mounting; allow for more frequent refills. |
| 100 litres | Mounted sweeping where refill access and carrier capacity suit the job. | Approximately 100 kg | Choose between rear-linkage and matched sweeper-mounted kits. |
| 200 litres | More water between refills at the same measured spray delivery. | Approximately 200 kg | Check full working load and kit-specific restrictions, particularly the forklift-only KM52 listing. |
Water weights exclude the tank, frame, pump, sweeper, collector and collected material. The tank’s position also affects the load carried by the linkage, loader and axles.
Use litres divided by litres per minute to estimate minutes of continuous spraying. Measure the delivery from all operating nozzles at the chosen setting. A pump’s maximum rating is not the actual spray consumption. Brush width, nozzle selection, intermittent use and the amount of damping required all affect refill intervals.
Get the whole setup working together
Water helps. Brush settings and collection finish the job.
Use enough moisture to bind fines
Aim for damp, collectable material. Excess water can turn soil and fines into sticky mud or slurry. These kits damp sweeping material; they are not pressure-washing systems.
Set the brush for the deposit
Use the lowest effective brush speed within the machine’s operating instructions. Set working height for the correct bristle contact; extra speed and pressure can throw material and increase wear.
Collect what needs to leave
Damping dust does not remove it. A matched collector takes the swept material away; windrowed fines left on the surface can dry and become dust again.
Use the correct guard
A compatible brush guard helps contain thrown material when working without a collector. Guarding and water serve different purposes. A guard is not a sealed, filtered dust-extraction enclosure.
Check every nozzle
Before sweeping, check the spray reaches its intended target, including the ends of the roller and any side-brush zone. A running pump does not prove that a blocked nozzle is delivering water.
Match power and mounting
The listed mounted kits use 12 V pumps. Confirm the vehicle supply, suitable connection, switching, hose routing and mounting components. Check the 5-litre kit separately; its listing does not specify electrical requirements.
Construction dust or other hazardous material? Identify what the dust contains and choose controls from the task assessment. An outdoor sweeper with a water kit is not a substitute for an appropriately rated dust-extraction system. Read HSE guidance on sweeping construction dust.

Common questions
Dust-suppression kit questions
Is spraying the brush better than spraying the ground?
It depends on where the dust starts. Brush wetting targets the bristles and their working zone. Ground spraying damps the deposit before contact, which can matter for an exposed side brush or a loose dry layer. Confirm the nozzle layout for the actual machine; some applications need coverage of both zones.
Does a rear-mounted tank only spray behind the tractor?
No. Tank position describes where the water is carried. Hoses feed the spray arrangement at the sweeper, which may be at the front of the tractor. The John Deere 3-Series case study combines a front sweeper with a WAS 200 KAT 1 tank.
Will the 5-litre kit fit every pedestrian sweeper?
Do not assume universal fit. Confirm the power unit, sweeper model, working width and collector arrangement. The WAS 51 K 1500 listing identifies a 5-litre sprayer but does not give a complete fitting matrix or electrical specification.
Can I fit the 200-litre KM52 kit to my tractor?
The current WAS 200 KM 52 listing explicitly says use only when mounted on a forklift. Do not specify it for a tractor on capacity alone. Ask Kersten to confirm an approved water system for your exact sweeper and carrier.
How long does a 100-litre tank last?
There is no single runtime for every installation. Divide usable tank volume by the combined measured nozzle delivery in litres per minute. The number of nozzles, settings, coverage and spraying duty all matter. At the same delivery, 200 litres provides twice the water volume of 100 litres, subject to usable capacity.
Will more water always reduce dust better?
Use enough water to damp the working material, then check the result. More water in the wrong place will not correct missed coverage and may create sticky mud or slurry. Check nozzle aim, brush speed, working height and collection before increasing delivery.
Can a water kit replace a collector or brush guard?
No. Water binds fines, a collector removes swept material and a compatible guard helps contain thrown debris. Specify each around the job. Water suppression does not make the sweeper a sealed or filtered dust-extraction machine.
What is included in the prices?
Prices shown are for the linked water-kit listings, excluding VAT. Confirm tank capacity, mounting frame, nozzles, hoses, pump, vehicle connection, controls and fitting in your quotation. The carrier, sweeper and collector are separate unless explicitly included.
