Ecoduct Pressure Calculator for Apartment Ventilation

EcoDuct | Pressure loss modelling for apartment exhaust systems

Apartment ventilation systems demand reliable airflow with minimal pressure loss. Bathroom, toilet and rangehood exhaust systems are particularly sensitive to duct resistance due to long runs, multiple branches and tight ceiling voids.

EcoDuct provides a pressure calculator purpose-built for EcoDuct PVC duct systems, enabling HVAC designers and contractors to assess pressure loss early and design apartment exhaust systems that perform as intended.

The EcoDuct pressure calculator supports accurate exhaust design from concept through documentation, installation and commissioning.

EcoDuct Pressure Calculator – Apartment Applications

The EcoDuct pressure calculator allows users to estimate pressure loss for:
– Apartment bathroom exhaust systems
– Apartment toilet exhaust systems
– Residential kitchen / rangehood exhaust systems

The tool considers key variables such as:
– Duct size and length
– Various of fittings

Unlike generic duct calculators, this tool reflects the sizes, material properties and internal surface characteristics of EcoDuct, providing more representative results for PVC duct installations commonly used in apartment buildings.

How the Tool Supports Apartment Ventilation Design

The calculator is typically used during:
– Early apartment services design
– Exhaust riser sizing and layout development
– Fan and exhaust unit selection
– Verification of low-pressure duct strategies

Benefits of the EcoDuct Pressure Calculator Across the HVAC-R Supply Chain

HVAC Designers & Mechanical Engineers

– Faster pressure-loss checks for apartment exhaust
– Improved confidence when specifying EcoDuct for wet-area exhaust
– Better alignment between duct sizing and fan static pressure

Mechanical Contractors

– Clear understanding of expected system resistance before installation
– Reduced risk of underperforming bathroom or rangehood exhaust systems noting that rangehooods  (where allowed under codes and standards) generally have poor pressure data
– Improved constructability in tight ceiling spaces

Builders & Head Contractors

– Reduced risk of late fan upgrades due to excessive pressure loss
– Improved cost certainty for apartment ventilation systems
– Fewer commissioning issues at practical completion

Why Pressure Calculations Matter in Apartment Exhaust Systems

In apartment buildings, poorly calculated exhaust systems can result in:
– Inadequate bathroom and toilet exhaust rates
– Poor kitchen exhaust capture and odour issues
– Increased fan noise and energy consumption
– Non-compliance with ventilation performance requirements

By using the EcoDuct pressure calculator, project teams can validate duct sizing early, support correct fan selection, reduce commissioning and defect risks, and improve long-term apartment ventilation performance.
