Products of FLOW company

Hero Product Section

Since 2018, FLOW has been an expert in the development and production of concealed linear slot diffusers and static pressure chambers (SPC), ensuring ideal air flow distribution in accordance with the highest Russian and international ventilation and air conditioning standards.

Each diffuser model was tested on special test benches in the acoustic and aerodynamic laboratories of the Moscow State Technical University (MSTU) named after Bauman. Based on these studies, we created tables for calculating noise, air speeds and pressure losses for each model.
Premium slot diffusers combine comfort, style and energy efficiency, and guarantee stable and silent operation of the system.

Our mission

— to create a technological product, aesthetics and comfort, as well as to ensure effective circulation of fresh air in the room.
We provide technical and design solutions that are suitable for various interior styles to our partners: design studios and architectural bureaus, interior designers, installers and designers, industry companies, developers, builders, and dealers of climate control equipment.

Model AF with light

Model AF with light

(Diffuser slot width 25–80 mm)

  • Combining ventilation and air conditioning systems with lighting into a single line. Minimizing the number of unnecessary lines on the ceiling. Achieving a perfect, functional minimalism.
  • Magnetic busbars or spotlights from our partners are attached to the rigid reflector of model AF, and all necessary electrical connections are made. The air flow is blocked only at the points where the lights are attached, either partially or completely.
  • All that remains at the site is to hang the finished diffuser with lighting from the ceiling, connect the air ducts, and connect the busbars to the electrical system.

Static pressure chambers (SPC) FLOW

РВ type 1

РВ type 1

Narrow Р-shaped static pressure chamber (plenum box)

  • The narrowest РВ type. Ideally suited for installing diffusers into walls, the end of ceiling bulkheads, or furniture panels, when the diffuser slot faces sideways rather than downward. Also used in situations with width limitations in the ceiling void, such as beams or other structural elements.
  • Welded sheet metal construction connected to the diffuser via sealing tape ensures maximum system airtightness.
    Unique profile guarantees perfect geometry.
  • Standard version uses sheet steel from 0.7 to 1.4 mm; stainless steel version available.
    Polymer powder coating protects against external elements and allows installation in high-humidity areas.
  • Black polymer powder coating by default; any RAL color available. Powder-coated SPCs are corrosion-resistant. Chambers can be additionally treated with antibacterial or antistatic compounds.
  • Diffusers are supplied pre-assembled with static pressure chambers and all necessary inlets for any ductwork. Simply suspend the entire unit from the ceiling and connect to ventilation and air conditioning systems. If necessary, a set of vibration hangers and surface-mounted inlets can be added for easier installation.
РВ type 2

РВ type 2

T-shaped static pressure chamber (plenum box)

Optimal Air Distribution.
Duct connections can be made from the side, opposite the slot, and/or from the end. Overall dimensions of the PB can be reduced by using oval connections.

The unit features a welded steel construction with powder-coated finish: corrosion-resistant, airtight, low-noise, and designed to minimize pressure loss. PB units may additionally be finished with powder coatings containing antibacterial or antistatic additives.

Each PB is supplied fully assembled with slot diffusers and all necessary duct connections for any type of air duct. Installation requires only suspending the entire assembly to the ceiling and connecting it to the ventilation and air-conditioning systems.

If required, the system can be complemented with a FLOW vibration-isolation suspension kit and FLOW surface-mounted duct connections for enhanced installation convenience.

SPC type 3

SPC type 3

T-shaped static pressure chamber with rounded corners (plenum box)

  • Optimal Air Distribution with Minimal Velocity Loss.
    Rounded corners reduce turbulence. Duct connections can be made from the side, opposite the slot, and/or from the end. Overall dimensions of the PB can be reduced by using oval connections.

    The welded sheet metal construction, coupled with a diffuser through a sealing tape, ensures maximum system airtightness. The unique profile guarantees precise geometry.

    Standard models are manufactured from sheet steel 0.7–1.4 mm, with optional stainless steel fabrication. The polymer powder-coated finish provides protection against environmental exposure and allows installation in high-humidity spaces. Powder-coated PB units are corrosion-resistant.

    Chambers can be additionally finished with antibacterial or antistatic powder coatings.

    Each PB is supplied fully assembled with slot diffusers and all necessary duct connections for any type of air duct. Installation requires only suspending the entire assembly to the ceiling and connecting it to the ventilation and air-conditioning systems.

    For enhanced installation convenience, the system can be complemented with a vibration-isolation suspension kit and surface-mounted duct connections.

SPC type 4

SPC type 4

Low plenum box

The Lowest-Profile PB Type for Ceiling Space Optimization.
Adapter height depends on diffuser slot width and the diameter of the applied duct connections. To minimize overall system height, the use of oval connections or small-diameter ducts is recommended.

The welded sheet metal construction, joined to the diffuser through a sealing tape, ensures maximum system airtightness. The unique profile guarantees precise geometry.

Standard units are made of sheet steel 0.7–1.4 mm, with an option for stainless steel fabrication. The polymer powder-coated finish protects against environmental exposure and enables installation in high-humidity environments. Powder-coated PB units are corrosion-resistant.

Chambers may be additionally treated with antibacterial or antistatic powder coatings.

Diffusers are supplied pre-assembled with plenum boxes, complete with all required duct connections for any air duct type. Installation requires only suspending the entire assembly to the ceiling and connecting it to the ventilation and air-conditioning systems.

SPC type Z

SPC type Z

Plug on the false element

End Cap with Dummy Element for Airflow Separation.
Designed to prevent air transfer, the dummy element is used where a continuous linear appearance must be preserved while dividing the diffuser into active and inactive sections. This solution allows bypassing protruding building elements or balancing the supplied airflow by reducing the active length of a continuous diffuser.

The welded sheet metal construction, connected to the diffuser with sealing tape, ensures maximum system airtightness. The unique profile guarantees precise geometry.

Standard units are manufactured from sheet steel 0.7–1.4 mm, with optional stainless steel execution. The polymer powder-coated finish protects against environmental exposure and enables installation in high-humidity environments. Powder-coated PB units are corrosion-resistant.
