PD2 duct cleaner: entry model for maintenance

What do you know for certain about the PD2 duct cleaning tool?

In short: the PD2 is part of the Lamers range, in the air duct cleaning category, alongside the DC4, the PD4 and the Intelligent Airnozzle. Lamers has supplied professional cleaning equipment for industrial cleaning and maintenance for more than fifty years, both standard and customised. That much is established.

What you will not get from this page: the diameter range, shaft length, drive, weight or price of the PD2. Those details could not be verified, and a wrong size costs you more than a phone call. If you come across figures without a source, it is wise to have the supplier confirm them first.

What you can do is get a sharp picture of your own situation. The better you know which ducts you have, the faster Lamers can tell you whether the PD2 fits or whether another model makes more sense. The following sections cover exactly that.

Which questions should you ask Lamers about the PD2 duct cleaner?

Use this list as a call script. Ask about every point and write the answer next to it, so you can compare the PD2 fairly with the other machines.

Two extra questions people often forget: which parts are included as standard and which you have to order separately, and how you transport and store the machine. This page deliberately gives no answer to those, because only Lamers can.

When does a compact duct cleaner suit your work?

A compact machine is interesting if you mainly deal with short duct sections, individual exhaust points or recurring maintenance. Think of a facilities team that looks after the exhaust ducts of toilet and washroom areas itself, or an installer who wants to include the first stretch of duct behind a valve during a service visit.

A compact machine makes less sense if you have long horizontal runs, large cross sections or heavy contamination. There you want reach and a shaft that keeps the brush in the centre of the duct. That is exactly what the DC4 duct cleaning machine is made for: according to Lamers it reaches up to 30 metres in ducts from 100 to 600 mm, including vertical runs and 90 degree bends.

Three example situations

• Fictional example 1: a school with a short exhaust duct per classroom leading to a central shaft. Here it is all about many short jobs in a row. Ask Lamers whether the PD2 is intended for that.
• Fictional example 2: a distribution centre with long supply ducts above the racking. A short shaft will not get you far enough here, and a machine with more reach is more logical.
• Fictional example 3: an office with thin flexible connections to ceiling grilles. Here compressed air with a camera may suit better than a brush.

PD2, PD4, DC4 or Airnozzle: how do you compare duct cleaners fairly?

Put the machines side by side on the points that matter for your ducts. Fill in the PD2 column after your conversation with Lamers.

Sources: Lamers and Danduct Clean, reference date 6 October 2026. The manufacturer describes the PD4 duct cleaner as very easy to handle and suitable for small ducts. If you want all machines and their accessories in one overview, look at the full range of duct cleaning equipment.

How do you survey your ducts before choosing a PD2 duct cleaner?

A good machine choice does not start in the catalogue but in the ceiling void. With these five steps you will have the data Lamers needs in a single afternoon.

1. Draw the runs. Use the installation drawing or walk the route. Note where each run starts and ends.
2. Measure cross sections. For each run, the smallest and largest diameter, or width and height for rectangular ducts.
3. Count openings. A Eurovent recommendation mentions inspection openings at most 10 metres apart, or after no more than two bends of 45 degrees or more. The further apart the openings, the more reach you need.
4. Identify the material. Sheet steel, flexible duct or duct board. That determines whether you choose a soft or a stiffer brush.
5. Describe the dirt. Dry dust, grease, construction dust or something sticky. According to Eurovent, dry methods are usually sufficient for supply and general exhaust, but exhaust from commercial kitchens calls for wet methods.

With those five answers Lamers can tell you concretely whether the PD2 is the right machine. If you are unsure about the dirt itself, first read about the duct cleaning method.

What else do you need besides the PD2 to clean ducts?

A brushing machine loosens dirt but does not remove it. Without extraction, the airflow blows the loosened dust further into the system or out into the room. Cleaning contractors therefore work under negative pressure and seal off sections of the duct.

• Duct plugs: balloons to seal off a duct section and caps to cover valves and grilles. More on this under sealing balloons and vent caps.
• Extraction with a filter: a unit that puts the duct under negative pressure and filters the dust.
• Brushes: a set in the sizes of your ducts, with the right stiffness. See choosing the right duct brush.
• Access: inspection hatches in sensible places, so you can insert the machine.

So when you ask for a quote, do not just ask Lamers about the PD2 but about the complete package you need to deliver a duct clean from start to finish.

Which misconceptions about compact duct cleaners do you often hear?

Misconception 1: a small machine is always the cheap option. Not if it means having extra hatches fitted or returning twice. Calculate the whole job, including access and extraction. Indications of what an outsourced clean costs can be found under what duct cleaning costs.

Misconception 2: what you cannot see is clean. KHN (Royal Dutch Hospitality Association) points out that serious contamination is often not visible to the naked eye. A brush without a check afterwards therefore gives you no certainty.

Misconception 3: every brush fits every machine. Shafts and couplings differ per type. So always ask which brushes belong with the PD2.

Misconception 4: a machine replaces the maintenance plan. How often you clean depends on the building and how it is used. A guideline per situation can be found under duct cleaning frequency.

Who should consider asking about the PD2 compact duct cleaner?

The PD2 is worth considering for organisations that do their own maintenance and do not need a complete fleet of machines. For example facilities teams of schools, care locations or offices, and installers who maintain ventilation and want to include the duct as well.

For companies whose main activity is air duct cleaning, a combination of machines is more logical, because they encounter different ducts in every building. That is covered on the page about equipment for cleaning contractors.
