LEV HUB Documentation

Welcome to LEV HUB, the next-generation platform for designing, managing, and monitoring Local Exhaust Ventilation systems. Our platform combines advanced engineering tools with AI-driven assistance to streamline compliance and design workflows.

Creating Your First LEV System

Getting started with LEV HUB is simple. Follow these steps to design and analyze your first system:

  1. Sign Up & Log In: Create your account to access the dashboard and design tool.
  2. Start a New Project: From the main dashboard, select "Create a System". You will be prompted with a disclaimer regarding the tool's calculations.
  3. Define Building Parameters: Use the "Edit Building" tools to set the dimensions of your workspace. This creates the canvas for your design.
  4. Add Equipment: Place your primary equipment, such as filtration units and fans, onto the canvas. Use the inspector panel on the right to configure their properties.
  5. Place Extraction Points: Add extraction points where contaminants are generated. Specify the required airflow (m³/h) and static pressure (Pa) for each point.
  6. Connect Components: Use the "Connect Objects" tool to draw ductwork between your extraction points and main equipment. The tool will automatically add necessary fittings like bends and junctions.
  7. Recalculate & Analyze: Click the "Recalcalculate" button. Our AI will analyze the airflow dynamics, resize ducting for optimal velocity, and calculate the total system pressure.
  8. Generate BOM: Once you are satisfied with the design, generate a complete Bill of Materials and performance report.

Core Concepts

Systems: A "System" in our platform represents a complete LEV design, including hoods, ductwork, fans, and filters. You can have multiple systems for different areas or processes within your facility. Each system is an independent calculation environment.

Real-Time Monitoring: By connecting IoT-enabled sensors (available with Pro and Enterprise plans) to your physical LEV systems, you can stream real-time data to the LEV HUB dashboard. This allows for predictive maintenance, instant alerts on performance degradation, and detailed analytics for compliance reporting.

System Designer

The core of LEV HUB is our powerful System Designer. This 2D/3D environment allows you to lay out your facility, place fans, filters, and discharge stacks, and connect them with intelligent duct routing.

3D Canopy Configurator

Design custom extraction hoods with our interactive 3D Configurator. Adjust dimensions, spigot sizes, and material specifications in real-time. The tool automatically calculates the required airflow volume and static pressure based on your geometry and application type (e.g., Welding, Dust).

Engineering Calculators

We provide a suite of standalone calculators for quick checks and component sizing:

  • Extraction Calculator: Calculate hood flow rates and capture velocities.
  • Duct Calculator: Size ductwork, calculate velocities, and estimate friction losses for both circular and rectangular ducts.
  • Vex Calculator: Specialized tool for vertical discharge stack calculations.

AI Assistant (Bran)

Bran is your expert LEV guide, available 24/7. Use the chat interface on the dashboard to:

  • Ask technical questions about LEV design principles.
  • Get recommendations for capture velocities and transport velocities based on specific contaminants.
  • troubleshoot common system performance issues.

Bran is trained on a vast library of engineering standards (e.g., ACGIH, HSG258) and best practices.
