Key Considerations:

Air Velocity: Influenced by flow rate, diffuser type and size, and room configuration. Excessive velocity can cause drafts.
Sound Pressure Level: Should not exceed defined levels based on room type. Influenced by fans, fire dampers, air terminal units, and diffusers.

Application Guidelines: The guide includes a table for selecting TROX products based on air change rates per hour, with suitability ratings for constant and variable volume systems.

Technical Specifications: Detailed tables provide flow rates, throw distances, sound power levels, and pressure drops for various products, ensuring compliance with comfort and safety standards.

Order Codes and Customization:

Diffusers can be customized with different finishes, colors (RAL codes), and configurations (e.g., adjustable flow rate control, lip seals).
Standard finishes include powder coating to RAL 9010 and RAL 9006.

Performance Data:

Tables provide detailed throw distances and flow rates for each diffuser type and configuration.
Minimum flow rates are specified for each size and type.

Recommendations:

Ensure diffuser selection matches room dimensions and desired air distribution patterns.
Consider sound power levels and pressure drops in design calculations.

Specifications:

Weather Resistant Louvres:
- Types include WG, AWG, WGE, and AWK.
- WG: Made from galvanized steel with a bird screen and drilled flange.
- AWG: Made from extruded aluminum with similar features.
- WGE: Constructed entirely from stainless steel.
- AWK: Features anodized aluminum and a finer bird screen.

Rectangular Fire Dampers:
- Type FK-K90 and FK-K90-LD are available with various construction variants and accessories.
- Flow rates and sound pressure levels are specified for different sizes and pressure drops.

Circular Fire Dampers:
- Types FKR-01-K90 and FKR-02-K90 are available with powder-coated or stainless steel casings.
- Flow rates, pressure drops, and sound levels are detailed for various nominal widths.

Accessories and Attachments:
- Various attachments and accessories are available for different fire damper types, including fusible links and flexible connectors.
- Specific codes are used for ordering different configurations and accessories.

Specifications:
Circular silencers are available in types CA, CF, and CS with plug-type spigots. Insulation thickness options are 50 mm and 100 mm. The insertion loss varies by frequency and insulation thickness, with detailed values provided for different octave bands.

Procedures:
Sound pressure levels are measured in dB(A) and account for system attenuation. The document provides a detailed nomenclature for understanding the parameters involved, such as total pressure differential (∆pg), upstream velocity (v), and sound pressure levels (LpA, LpA1, LpA2, LpA3).

Standards:
The document references DIN V 24194 Part 2, Class II for low-leakage performance. It also mentions system attenuation details available in a specific leaflet.

Recommendations:
For optimal performance, the document suggests using the standard insulation thickness of 50 mm unless otherwise specified. It also provides order codes for specifying product configurations.

Data Summary:
Tables provide insertion loss values for different frequencies and insulation thicknesses, as well as dimensions and flow rates for various sizes. The document includes a selection table for splitter attenuators, detailing insertion loss and flow rates.

Key Information:
Critical parameters include the total pressure loss (∆pt) and the A-weighted sound pressure level (LWA). The document also lists international subsidiaries and representatives, indicating the global reach of the company.

5 Introduction In ventilation technology, two criteria are of particular importance: • the air velocity in the occupied zone and • the sound pressure level in the room Air velocity The air velocity depends on variables such as • flow rate in combination with type and size of the diffuser • arrangement of the diffusers within the room • the height of the room The flow pattern provided by the diffuser (swirl, linear or displacement) also influences the maximum possible air change rate. Drafts are caused by excessive air velocity in the occupied zone. The configuration tables in this Quick Selection...
