Smoke generators for pipes, sewer networks and airtightness testing

Smoke generators for pipes, sewer networks and airtightness testing

Smoke generators produce dense, visible smoke to inspect a network, detect an airtightness defect or locate an abnormal passage in a pipe. Used by sewer, diagnostic, maintenance and building professionals, they provide a simple, non-destructive method for testing ducts, drains, drainage networks, manholes and pipes. At Fluotechnik, we offer smoke generators suited to field interventions to make leak detection, airtightness testing and defect identification on networks easier.

Dense, visible smoke

Smoke makes it easier to quickly visualise air exits, airtightness defects or abnormal passages in a network.

Suitable for pipes and sewer networks

A useful solution for pipes, manholes, drains, buried networks, drainage systems and technical ducts.

Non-destructive method

Smoke testing helps guide the diagnosis without breaking, dismantling or unnecessarily opening installations.

Useful for leak and infiltration detection

Smoke generators can reveal defects that are sometimes invisible during a simple visual inspection.

Our range of smoke generators for airtightness tests and network diagnostics

To meet smoke testing, airtightness inspection and pipe diagnostic needs, Fluotechnik offers several solutions suited to field interventions. Depending on the type of network, the volume to be inspected, the site configuration and the required visibility level, you can choose a smoke generator adapted to your application. Each reference has been selected to produce dense smoke, make the test easier to read and help professionals identify airtightness defects, infiltrations, leaks or abnormal passages more quickly. This range allows you to compare the different smoke generators according to their format, emission duration, intensity, use and relevance for sewer networks, pipes, ducts or drainage systems.

What is a smoke generator for pipes used for?

A smoke generator for pipes produces visible smoke that circulates through a network in order to reveal a leak, infiltration, airtightness defect or abnormal communication between several areas. When smoke exits in an unexpected place, it highlights an air passage, crack, poorly sealed connection, faulty joint or anomaly in the network. This method is particularly used in sewer networks, drainage pipes, drainage systems, manholes, technical ducts and certain building installations.

A smoke test can help understand why odours rise inside a building, why a network seems to communicate with an unintended area, or where a loss of airtightness is located. This category is intended for professionals looking for simple, visual and effective equipment to inspect pipes without using destructive methods. Unlike dyes or liquid tracers, a smoke generator does not follow water flow: it makes smoke circulation visible within a volume, duct or network in order to identify abnormal exits.

Why choose a Fluotechnik smoke generator for pipes and sewer networks?

Choosing the right smoke generator means improving visibility, speed and precision during pipe or sewer network diagnosis. Fluotechnik selects products designed for professionals who need to test network airtightness, identify an anomaly or check communication between ducts. Our smoke generators provide clear visual reading while fitting easily into a field intervention method.

Visible smoke for fast reading

Dense smoke makes it easier to identify abnormal exits and airtightness defects.

Suitable for sewer networks

A useful solution for pipes, manholes, buried networks, drains, drainage systems and technical ducts.

Non-destructive diagnostic method

Smoke testing helps guide investigations without systematically breaking or dismantling installations.

Complementary to other diagnostic equipment

Smoke generators can be used alongside inflatable pipe plugs, tracers, detection kits or accessories depending on the context.

Simple field use

Implementation is quick and makes targeted inspections easier on worksites, networks or existing installations.

Expert technical support

Our team helps you choose the right solution according to the network to be inspected, the volume to be filled with smoke and the test objective.

FAQ on smoke generators for pipes and sewer networks

A smoke generator for pipes is a product or device that generates visible smoke in order to test a duct, drain or network. The smoke helps identify abnormal exits, airtightness defects, cracks or unintended communications.

A pipe smoke test is used to check the airtightness of a network, locate a defect, identify infiltration, inspect a connection or understand the source of odour problems.

Smoke generators can be used in pipes, drainage ducts, sewer networks, drains, manholes, buried networks, technical ducts or other conduits requiring visual smoke inspection.

Yes, it can help detect a leak or airtightness defect when smoke exits through an abnormal area. It is especially useful for identifying air passages, cracks, defective joints or poorly sealed connections.

A smoke generator makes smoke circulation visible in a duct or network. A liquid tracer is used to follow water flow. The two methods can be complementary depending on the type of diagnosis required.

Yes, smoke testing can help understand the source of certain odour problems by revealing connection defects, abnormal passages or communications between networks and indoor areas.

No. It is a non-destructive diagnostic method. It makes defects visible without systematically breaking, opening or dismantling installations.

It depends on the network and the objective of the test. In some cases, isolating a section with an inflatable pipe plug can improve smoke diffusion and make the test more precise.

Choosing the right smoke generator to test a pipe or sewer network

A smoke generator is particularly useful diagnostic equipment when an air passage, airtightness defect or abnormal communication in a network needs to be made visible. In pipes, drainage systems or sewer networks, some defects remain difficult to identify through simple visual inspection. Smoke makes the issue visible and helps guide the intervention more quickly.

Depending on the context, the choice of smoke generator will mainly depend on:

  • the type of network to be tested: pipe, drain, sewer network, drainage system, manhole or technical duct;
  • the volume to be filled with smoke and the required emission duration;
  • the diagnostic objective: airtightness test, leak detection, connection check or odour source investigation;
  • field conditions: accessibility, ventilation, network configuration and possible need for isolation.

By bringing together the main solutions related to smoke generators for pipes on one page, Fluotechnik helps you compare uses, better understand the value of smoke testing and select the reference best suited to your intervention.

Discover other equipment for tracing and network diagnostics

Depending on the type of network, the test objective and the diagnostic method required, smoke generators can be used alone or in combination with other Fluotechnik equipment. To isolate a section, follow a flow, prepare leak detection or structure a complete intervention, smoke testing can be combined with suitable tracers, inflatable pipe plugs or accessories.

Inflatable pipe plugs

To temporarily isolate a pipe, block a flow or prepare an airtightness test.
Inflatable pipe plugs
Inflatable pipe plugs make it possible to close a network section in order to better control the intervention. They can complement a smoke test by limiting smoke diffusion to the area being diagnosed.
