Many industrial sectors produce large amounts of fine dust particles. These flammable particle concentrations can be highly volatile in a confined space; They can burn with oxygen in the air when exposed to a spark, embers or similar ignition source. Facilities with the potential for fire or even explosion must use antistatic hoses.
Antistatic hose can be one of two types: static dissipative hose or static conductive hose. Ünveren A.Ş. manufactures both types of anti-static hose in various lengths and materials, with designs suitable for a wide range of environmental and temperature requirements.

Anti-static dust collection hoses
Explosion-proof vacuum hoses
It is important to make the appropriate selection for each type of anti-static hose and the
important roles they play.
Why Anti-Static Hose? Fine dust particles or chips carried by the hose can produce static electricity
when they rub against each other or the hose walls. The particles touch each other and then move
away from each other, transferring an electric charge between them. The friction produced by
these charged electrons can ultimately cause electrostatic discharge, or the familiar shock feeling
from static electricity, because there is an imbalance of electrical potential between the particles.
In manufacturing environments that create, transport or process fine dust, a seemingly harmless
spark of static electricity can trigger explosions. Static also causes materials to clump together and
can clog your hose.. When proper static-dissipating hose materials and proper grounding are used
during installation, durable and flexible anti-static hoses can maintain maximum airflow and
prevent static electricity from building up in the hose or its contents, reducing the risk of these
potential hazards .
What Makes a Hose Anti-Static?
For anti-static hoses, manufacturers must choose materials that will meet the exact need. For
example, since hose applications vary from light to heavy-duty, it is important to choose a material
that has sufficient durability and weight for your needs.
Ünveren A.Ş. produces hoses with different features for the different needs listed below.
Resistance to wear, tear, crushing, chemicals and corrosion
Ability to perform over a wide temperature range
Durability
Good tensile strength
Flexibility
High vacuum tolerance
If products such as pharmaceuticals or consumables are used, materials acceptable to FDA
standards with food compatibility certification
Antimicrobial properties
Anti-static hose materials will either be static dissipative or static conductive. The majority of our
products are urethane with a static dissipative material. This allows non-conductive urethane to
safely dissipate electrical charge while resisting tearing, abrasion, and chemicals.
Grounding is equally important in terms of what makes the hose anti-static. Since anti-static air
hoses, material hoses and related varieties need to discharge static electricity and this requires
careful control, manufacturers often integrate a ground wire into the structure of the hose. This
ground wire provides a safe path for static electricity to follow, helping to prevent a dangerous
buildup that can trigger painful shocks at best or destructive sparks at worst. To discharge
electricity safely, antistatic hoses and conductor cables must be properly grounded.
Static Dissipative Hoses and Static Conductive Hoses
Static dissipative and static conductive hoses do the same job and produce the same result; In
other words, it prevents the formation of unwanted static electricity. However, where the two
types of anti-static hoses differ is in how they do this.
Hoses composed of static conductive materials prevent the build-up of static electricity by
providing less electrical resistance (higher conductivity) than surrounding components, essentially
helping to draw the charge from the hose and releasing it through proper grounding. Typical
applications include industrial anti-static vacuum cleaners and woodworking installations.
Static dissipative hoses, on the other hand, eliminate static electricity with a higher resistance hose
material; This means that electrical charge flows through a material in a controlled, slower manner.
The material itself helps prevent static electricity by spreading the charge across the hose surface
to prevent any discharge from becoming large enough to cause ignition.
Applications of Static Dissipative Hose
The design of static dissipative hose, often referred to as anti-static hose, is to reduce or prevent
static electricity by dispersing it through rubber material to the hose ends.
The most common applications are:
: Wagon loading/unloading
Industrial vacuum cleaners, pharmaceutical, static dust control, woodworking/furniture
: Applications requiring abrasion resistance, dust collection, food grade, static control, vapor
recovery, woodworking/furniture
: Clean rooms, dust collection, fertilizer spreading, food grade, glass riveting, granule handling
: Grain vacuum, plastic pellet transfer, dust and bulk, static control, surface preparation dust
collection
: Industrial vacuum cleaners, concrete floor cleaning, granule handling, injection molding, plastic
pellet transfer, food grade
: Automatic toll booths, bus ventilation, concrete floor cleaning, cable duct, industrial vacuum
cleaners, paper coating duct, printing, sprayers, static control, ventilation
: Static control for dust and fumes
Why Are Anti-Static Hoses Important?
Dust ignition explosions are a concern in numerous industries across the country. Unless
businesses comply with static and dust regulations, they increase the risk of extensive property
damage as well as employee injury or death.
Although not a comprehensive list, the risk of explosion from dust is higher than normal in
applications with these environmental factors:
Agricultural powders: Wet corn, sorghum and other grains; Sugar refining; flour and grain grinding
Carbonaceous powders : Coal, graphite, grapheme, nano/mesoporous carbons
Chemical powders: NOC fatty acids, essential oils, gelatin
Metal powders: Milling, plating, polishing, anodizing and coloring
Plastic powders : Synthetic resins and non-vulcanizable elastomers
Our anti-static dust collection hoses and static control hoses play a critical role in ensuring
operational safety and preventing fires and explosions. We help our customers select flexible hoses
with the best electrical resistance values and appropriate static control hoses to suit the unique
risks associated with their facilities and operations.
