FEVI portable filter units for sandblasting dust
FEVI portable filter units are mobile solutions dedicated to the extraction and suppression of dust produced during sandblasting operations.
They are recommended when sandblasting is carried out in enclosed spaces, confined environments or industrial sites where dust tends to accumulate quickly, reducing visibility and making the operation more difficult to manage.
Unlike a fixed system, a portable filter unit can be moved and positioned close to the working area.
This feature makes it suitable for variable operations, industrial maintenance, off-site work, temporary worksites and applications where logistical flexibility is essential.
The current FEVI page describes these systems as compact, easily movable units suitable for situations where fixed dust extraction cannot be installed.
Who they are recommended for
- Companies carrying out sandblasting in confined environments
- Industrial and shipyard worksites
- Maintenance operators working inside tanks, vessels or ducts
- Companies sandblasting inside technical rooms, containers or industrial basins
- Companies using open blasting machines in enclosed spaces
- Industrial departments that need to improve dust management
- Operators requiring a mobile and portable system
- Companies that want to reduce cleaning time after the operation
Main applications
Sandblasting inside tanks and vessels
During internal sandblasting of tanks and vessels, dust can accumulate quickly and compromise visibility.
A portable dust control system makes it possible to extract and filter dusty air, making the work easier to manage.
Sandblasting inside ducts and pipes
Industrial ducts and pipes are complex environments, often with limited access.
FEVI portable filter units are recommended when a compact, mobile solution adaptable to restricted spaces is required.
Technical rooms and confined environments
In technical cabins, containers, industrial basins and enclosed rooms, dust can remain suspended and make the operation more difficult.
The filtering system helps control dispersion and improve operating conditions.
Industrial worksites and maintenance operations
On industrial worksites, the configuration of the working area can change frequently.
A portable filter unit allows the system to be moved according to the position of the operation.
Open blasting in enclosed spaces
When an open blasting machine is used in enclosed or partially confined environments, dust control becomes even more important.
Temporary and off-site operations
The compact and movable structure makes the system suitable for variable operations and non-permanent work.
Why choose a FEVI portable filter unit
Mobile and easy-to-position system
The system can be brought close to the working area, a useful feature for worksites and industrial maintenance operations.
Recommended for confined environments
Designed for work inside tanks, vessels, ducts and technical rooms where air management is essential.
Cartridge filtration
Polyester cartridge filtration retains dust generated during sandblasting.
Self-cleaning with compressed air pulses
The automatic self-cleaning system helps maintain efficient filtration during operation.
Compact structure
Optimized dimensions make transport, handling and use easier even in difficult spaces.
Controlled residual emissions
The FEVI page indicates residual emissions below 3 mg/Nm³.
Industry 4.0-ready
Possibility of integration with remote monitoring, automatic cleaning cycle management and digital operation control.
How sandblasting dust control works
During sandblasting, the abrasive jet removes paint, oxidation, residues, deposits or surface contaminants.
This action generates dust made up of removed material, abrasive fragments and fine particles.
The portable filter unit extracts dust-laden air from the working environment and conveys it to the filtration system.
The cartridges retain solid particles, while the compressed air pulse self-cleaning system helps keep the filtering surface efficient.
The result is a more controlled environment, with improved visibility and lower suspended dust accumulation compared to an operation without dedicated extraction.

When to choose a portable dust control system
- You need to sandblast in enclosed or confined environments
- You work inside tanks, vessels, ducts or technical rooms
- You cannot install a fixed dust extraction system
- You need to move the system between different operating areas
- You want to improve visibility during sandblasting
- You want to reduce dust accumulation in the working environment
- You need to support an open blasting or pressure sandblasting machine
- You work in industrial maintenance or temporary worksites
- You are looking for a compact and portable solution
- You want to integrate the system into an advanced monitoring logic
When to consider another FEVI solution
-
Blast room
For large-sized parts and dedicated environments with abrasive recovery and integrated dust extraction.
-
Blasting cabinet
For small or medium-sized parts, with the operator working from the outside through gloves and a viewing window.
-
Recovery sandblaster
When abrasive needs to be contained and recovered directly from the treated surface.
-
Water Blast
When the main objective is to reduce dust by using water during sandblasting.
-
Dedicated industrial vacuum cleaners
For collecting dust, residues and materials not directly related to sandblasting.
Safety and working environment assessment
Dust control must not be considered as an isolated element, but as an integral part of planning the operation.
Before choosing the system, it is important to assess:
- Type of surface to be treated
- Material removed during sandblasting
- Abrasive used
- Amount of dust generated
- Volume of the environment
- Presence or absence of external exhaust
- Available access points
- Need for handling and movement
- Working times
- Personal protective equipment
- Any worksite or plant requirements
In confined environments, the choice of the extraction and filtration system must be linked to an overall technical assessment.
