CENTRAL SYSTEMS
Engineered with the best vacuum unit
Regenerative
blower
Regenerative (side-channel) blowers are a top choice for industrial central vacuum systems when you need oil-free, quiet, continuous airflow with low maintenance.
Read more
They generate airflow by accelerating air through a high-speed impeller and repeatedly recirculating it in a side (toroidal) channel, creating a smooth, non-pulsating flow. Because there’s no internal lubrication, the air stream stays clean and uncontaminated—ideal for centralized systems where reliable long-term operation matters.
- Oil-free airflow (no internal lubrication)
- Pulsation-free flow with low vibration and low noise
- Minimal maintenance and strong fit for continuous-duty industrial operation
roots vacuum
pumP
Roots (rotary lobe) vacuum blowers are used in industrial central vacuum applications when you need high airflow and rugged positive-displacement performance—especially on demanding systems.
Read more
A Roots-style rotary lobe machine is a positive-displacement blower that delivers a largely consistent displacement per revolution, making it a proven choice for durable, low-maintenance industrial service. In many vacuum applications, Roots units are used as vacuum boosters—often paired with a backing pump—to move large volumes efficiently and support deeper vacuum performance when required.
- Positive-displacement rotary lobe design (high capacity / durable)
- Commonly used as a vacuum booster for faster evacuation and higher system throughput
- Vacuum capability depends on configuration; some rotary positive blower designs list vacuum performance up to ~24″ Hg in vacuum service
Toroidal channel
turbine
TBT blowers/exhausters are a high-performance option for centralized vacuum and airflow systems when you want side-channel style simplicity with performance that can approach positive-displacement behavior—without the typical noise and vibration.
Read more
TBT machines use a peripheral toroidal channel similar to side-channel blowers, but with an advanced impeller/channel design developed through extended research and testing. Like side-channel machines, they create a series of vortices and repeated recompression along the channel, producing a linear pressure rise. The advantage is strong performance with a smoother operating profile that supports industrial uptime.
- Peripheral toroidal-channel principle with repeated recompression along the channel
- Impeller/channel design aimed at high performance with lower noise and reduced vibration
- Minimal maintenance profile typical of contactless airflow machines
hight pressure
centrifugal fun
High-pressure centrifugal fans are a go-to for dust collection systems when you need high airflow (CFM) through ductwork and filters—without needing deep vacuum levels.
Read more
They generate airflow by accelerating air radially through a rotating impeller, converting velocity into static pressure to overcome resistance in ducting, filters, and dust collectors. This makes them ideal for centralized dust collection layouts where airflow and transport are the priority, while true vacuum sources (blowers/pumps) are typically used when higher vacuum is required.
- Designed to overcome ductwork + filter resistance in dust collection and conveying systems
- Best fit for high CFM / lower vacuum applications (material capture, ventilation, dust collectors)
- Commonly used as the airflow engine in dust collector systems and industrial air movement
Filter systems
is the key
M Class Main Filter
(EN 60335-2-69)
M Class filtration is designed for the safe collection of medium-hazard dusts commonly found in industrial environments.
Read more
With a filtration efficiency of ≥ 99.9%, it ensures reliable protection of the vacuum unit, stable airflow, and long filter life even during continuous operation.
Using M Class filters as the main filtration stage reduces clogging, minimizes pressure drop, and guarantees compliance with workplace safety standards for industrial dust extraction.
H Class Secondary Filter
HEPA H14
The H Class HEPA H14 filter provides the highest level of air purification, with a filtration efficiency of ≥ 99.995%.
Read more
Installed as a second filtration stage, it captures the finest and most hazardous particles, preventing any harmful dust from being released back into the environment.
This level of filtration is essential for applications involving toxic, carcinogenic, or very fine dust, ensuring maximum operator safety and full compliance with the most stringent health and safety regulations.
Why Proper Filtration Is Critical in an Industrial Central Vacuum System
A high-performance filtration system is essential for any industrial central vacuum system used in dust collection applications. Proper filtration protects the vacuum unit, maintains constant airflow, and ensures compliance with workplace health and safety regulations.
Poor filtration causes rapid filter clogging, airflow loss, increased energy consumption, and premature wear of blowers or fans. Most importantly, it can allow hazardous dust to be released back into the work environment.
Airflow-to-Filter Surface Ratio
The Key to Stable Performance
The airflow-to-filter surface ratio directly affects the efficiency and reliability of a central vacuum system. When airflow is too high for the available filter area, air velocity increases, leading to:
- Faster filter clogging
- Higher pressure drop
- Reduced suction performance
- Shorter filter service life
An adequately sized large filter surface reduces air velocity, improves dust separation, and ensures consistent airflow and vacuum performance, even in continuous industrial use.
to keep everything under control
Real-Time Performance Diagnostics
Critical data, including inverter frequency and pressure levels, are displayed through intuitive graphical gauges for immediate visibility. This allows for the constant monitoring of mechanical efficiency and operational health.
Optimized Filtration Efficiency
Users can easily customize automatic filter cleaning cycles, including specific post-operation settings, to maintain peak suction power. This proactive approach ensures filters remain clear and extends the overall lifespan of the filtration system.
Smart Material Disposal
The interface allows for the precise configuration of material discharge timing, adapting to the specific flow of the production line. This ensures that the collection and disposal process is fully synchronized with the system’s workload.

Depureco helps you from the design to the installation
A complete Central Vacuum System (CVS) is composed of four main components: the suction unit, filtration unit, discharge system, and pipework network.
To engineer a central vacuum system that meets the specific needs of an industrial facility, several technical parameters must be carefully evaluated. A key design factor is the distance between the vacuum drops and the location of the suction unit, as this directly affects system losses and performance. Equally important is determining the number of operators required to work simultaneously, as this defines the total airflow demand.
The length and diameter of the flexible hoses used at each vacuum point must also be defined, as these elements influence pressure losses and conveying efficiency. Based on this data, it is possible to calculate the required vacuum level (inH₂O) and airflow (CFM) needed to achieve the correct air velocity for material transport within the pipework.
