Vacuum conveying and its great benefits
Vacuum conveying is a modern way of transporting powders and granules with a number of benefits.
Reduce product scrap and product contamination
When using a vacuum conveyor your customers are working with an enclosed system where they will not have any
foreign material mixed in or have any product falling off the sides into the surrounding area. It is also a very gentle way
of transporting the product, meaning that the product will be intact/not damaged throughout the whole transportation
process. The velocity is adjusted depending on the product’s fragility – giving your customer minimum product scrap.
The vacuum conveying solution has a small plant floor footprint since the tubing can go strictly vertical from the point of
suction. The tubing is normally mounted in level with the discharge point and therefore not in conflict with other
machinery. This means that your customer can utilize the space in a more cost efficient way.
Our vacuum conveyors have very few moving parts, meaning that the service and maintenance cost is kept at a very
low level without needing to compromise on the reliability of the system. You can disassemble the conveyor body
without using tools. The pump unit is designed with a separate vacuum module that can easily be removed for
cleaning, resulting in reduced downtime.
Dust free working environment
When comparing with mechanical conveying systems such as screw and
belt conveyors – another important advantage of the vacuum conveying
is a dust free working environment. As vacuum conveying is an enclosed
system you will be able to improve the working environment, and it will
also give you the possibility to convey materials that are hazardous to
inhale that needs to be contained.
By replacing just a few parts of the modular vacuum conveying solution, one can easily change the installation in order
to increase conveying distance, change the plant layout or enhance the system capacity at a very reasonable cost.
This gives a future proof installation without compromising the reliability of the system.
Vacuum is created with compressed air through COAX®
technology (A). The pump can be automatically controlled.
The bottom valve (B) closes and the vacuum increases in
the container (C) and the conveying line (D).
The product is carried away from the feed station (E) into
the conveying line and then to the container.
The filter (F) protects the pump and the surrounding area
from dust and small particles.
During the conveying time, the air shock tank (G) is filled
with compressed air
At a preset time, the pump and the conveying are stopped
and the bottom valve (B) is opened. The product is
discharged at the same time as the air shock is activated
and the compressed air cleans the filter from dust and
When the pump starts again, this process is repeated and
a new cycle starts. The suction time and emptying times
are normally controlled by a pneumatic or an electric
Food Grade Vacuum Conveyors
Our food grade conveyors are designed to meet the
demands of industrial food grade applications with a
stainless steel body and seal indirect product contact
zones. They provide high throughput performance in a
small footprint and are equipped with a COAX technology
pump providing the most energy efficient way to produce a
Capacity Range: Up to 4 tons/hr
Premium Vacuum Conveyors
Our premium conveyors are designed with a stainless
steel body (ASTM 316L) to meet the very high hygienic
demands. Our premium technology is offered particularly
for our customers in the food and pharmaceutical industry
and where there is a big demand on high throughput
performance with a small footprint. Our premium vacuum
conveyors come with a COAX technology pump providing
the most energy efficient way to produce a vacuum.
Capacity Range: 2-liter batch volume up to 56 liters
Industrial Vacuum Conveyors
The general industry often handles abrasive powders that
require specially designed equipment. Our conveyors are
designed with stainless steel body (ASTM 304) to resist
parts wear of parts. Our industrial vacuum conveyor is
widely used in the general industry and sometimes in the
chemical industry. It has a high throughput performance as
well as a small footprint and is equipped with a COAX®
technology pump for maximum energy efficiency.
Capacity Range: Up to 4 tons/hr
