PROMETHEUS ATEX floor nozzle with steel connector in antistatic black rubber and stainless steel for Zone 21 and Zone 22 – 400 mm width

Used together with

PROMETHEUS is a robust floor nozzle for continuous vacuuming of floor surfaces in ATEX-classified production environments. The construction combines stainless steel and steel with antistatic rubber contact parts that ensure equipotential bonding throughout the system. Adjustable wheels maintain correct working height for even, efficient coverage of large floor areas. The steel connector version connects via quick-fit to double bend floor wands.

Applications

PROMETHEUS ATEX is designed for continuous floor vacuuming in explosion-classified production environments where flammable materials are handled in powder or dust form. Typical industries:

Food production — flour, starch, sugar, grain and granulate
Chemical industry — explosive powder and granulate
Woodworking — sawdust and fine wood dust
Metal processing — aluminium and magnesium powder
Coal processing — coal and coke dust

Important: PROMETHEUS ATEX is not ATEX-certified as a product. The antistatic rubber contact parts (version A) enable equipotential bonding within a complete ATEX-approved system. It is the installer’s and user’s responsibility to verify suitability for the specific ATEX-classified environment, zone and dust class.

Connection: Swivel connector

The swivel connector version has a rotating coupling that allows 360° free rotation between the floor wand and the nozzle. The wand is pushed directly into the swivel coupling. Significantly reduces operator strain when working with long or heavy hose runs. Requires double bend floor wands without coupling (PWF series).

Swivel connector 360° rotation

Rotating swivel coupling — the wand is pushed directly in. Provides 360° freedom of movement. Requires PWF series floor wands without quick-fit coupling: PWF50PD (Ø50), PWF40PD (Ø40), PWF38P2C (Ø38).

Prefer steel connector?? Alternative

The steel connector version has a fixed quick-fit stud and is preferred for fixed workstations. See PROMETHEUS steel connector →

Variant: Bristle strip

Dry dust and powder

The bristle variant has PP bristle strips along the full width of the nozzle. Available in two bristle types: plain polypropylene (PPL) for standard ATEX use, and polypropylene with brass wire (PPLBR) for increased conductivity and finer dust collection.

(RS) = bristle strip + swivel connector | (A) = ATEX antistatic rubber version | PPL = polypropylene | PPLBR = polypropylene + brass

Compatible floor wands: PWF50PD, PWF40PD, PWF38P2C

Variant: Squeegee (rubber lip)

Liquids and semi-fluid materials

The squeegee variant has a rubber lip along the full width of the nozzle. Available with grey rubber lip (L) for general use or black ESD rubber lip (L)(A) with antistatic properties for ATEX Zone 21 and Zone 22. The lip seals against the floor surface for effective collection of liquids and semi-fluid materials.

Materials and construction

Structure

Stainless steel + steel

Body in stainless steel and steel. Adjustable wheels maintain correct and even working height. Colour: black and zinc-steel. Temperature range: −20°C to +100°C.

Contact material (ATEX version A)

Antistatic rubber (ESD)

PP+brass bristle strips (PPLBR) and black ESD rubber squeegee lip both have antistatic properties. The combination of stainless steel and antistatic rubber enables continuous equipotential bonding in ATEX Zone 21 and Zone 22.

Frequently asked questions

When is swivel connector preferable to steel connector??

The swivel connector is best for mobile vacuum systems and centralised systems with long hose runs, where the operator works over large areas with frequent direction changes. It significantly reduces strain. The steel connector is preferred for fixed workstations with shorter hose runs and direct connection to quick-fit floor wands.

When should I choose the bristle variant over the squeegee?

The bristle variant (S) is best for collecting dry dust, powder and granulate on hard floor surfaces. The squeegee variant (L) is best for collecting liquids, semi-fluid spills and wet-lying materials. For ATEX use, always specify the (A) version with black ESD rubber lip.

What is the difference between PPL and PPLBR bristles?

PPL is plain polypropylene suitable for standard ATEX floor cleaning. PPLBR is polypropylene with interwoven brass wire, which increases the bristles’ conductivity and improves collection of finer dust particles. PPLBR is recommended in environments with very fine dust such as flour, starch and cement dust.

Is PROMETHEUS ATEX-certified?

PROMETHEUS ATEX is not ATEX-certified as a product. The antistatic rubber contact parts (version A) enable equipotential bonding within a complete ATEX-approved system. It is the installer’s and user’s responsibility to verify suitability for the specific ATEX-classified environment and zone.

Which floor wand dimensions are compatible?

PROMETHEUS swivel connector is available in Ø38, Ø40 and Ø50 mm and uses swivel connector. Compatible double bend floor wands: PWF50PD (Ø50), PWF40PD (Ø40) and PWF38P2C (Ø38) in chrome and stainless steel without coupling.

Is PROMETHEUS available in a Food/Pharma version?

PROMETHEUS is only available in the ATEX version. For food and pharma environments with FDA requirements, we offer ICEBERG — the same construction but in stainless steel with FDA-compatible silicone contact parts (Wacker R 4001 80, FDA 21 CFR 177.2600, BfR Recommendation XV).
