Vent-Axia 443028L Lo-Carbon Sentinel Kinetic Plus B Left Hand MVHR Unit

Product Description

The Vent-Axia 443028L Lo-Carbon Sentinel Kinetic Plus B Left Hand MVHR Unit is a high-performance Mechanical Ventilation with Heat Recovery (MVHR) system designed to deliver continuous, energy-efficient ventilation for residential and multiple-occupancy properties. Ideal for larger homes, care homes and student accommodation, this advanced heat recovery unit helps maintain indoor air quality while reducing heat loss through ventilation.

Featuring high-efficiency backward-curved impeller technology, the Sentinel Kinetic Plus provides powerful airflow with low energy consumption and quiet operation. Capable of delivering up to 400m³/h at 150Pa, the system can serve properties with up to ten bathrooms and a communal kitchen while achieving almost 90% heat recovery under specified operating conditions.

The integrated digital controller simplifies commissioning and system configuration, while Building Management System (BMS) connectivity enables convenient monitoring of ventilation performance. Built-in self-diagnostic functionality supports easier fault identification and maintenance planning.

Designed for installation flexibility, the unit features repositionable duct spigots, horizontal duct connection options and a unique folding filter that allows easy removal in restricted spaces. Its lightweight construction makes handling and installation more convenient, particularly in cupboards and confined locations.

Recognised in the SAP Product Characteristics Database (PCDB), the Vent-Axia Sentinel Kinetic Plus B is an effective ventilation solution for modern new-build developments and larger residential applications.

High-Efficiency Heat Recovery Performance

The Lo-Carbon Sentinel Kinetic Plus range incorporates advanced backward-curved impeller technology to deliver high airflow performance while minimising energy consumption and operating noise. By transferring heat from extracted indoor air to incoming fresh air, the MVHR system helps reduce ventilation-related heat loss and supports a comfortable indoor environment.

With airflow performance of up to 400m³/h at 150Pa, the unit is suitable for demanding residential ventilation requirements, including larger properties and multiple-occupancy developments.

Ideal for Care Homes & Student Accommodation

The Sentinel Kinetic Plus is particularly suited to larger residential buildings and shared accommodation. Its high airflow capacity allows ventilation system designs serving multiple bathrooms and communal kitchen areas, making it a practical choice for care homes, student accommodation and larger domestic properties.

BMS connectivity enables building managers and maintenance teams to monitor system status and optimise ventilation performance. Integrated self-diagnostics can also help identify faults, simplifying maintenance and reducing troubleshooting time.

Flexible Ducting & Installation

The Vent-Axia 443028L offers versatile duct connection arrangements to accommodate different building layouts. Repositionable spigots allow horizontal connections or a combination of horizontal and vertical ducting, helping installers maximise available space.

The standard duct connection size is 125mm, with optional 180mm and 200mm spigots available for installations using larger ductwork. The lightweight unit is designed to simplify handling, positioning and installation.

Quick-Change Folding Filter

The innovative folding filter design allows filters to bend during removal, making maintenance easier where access is restricted. This is particularly beneficial when the MVHR unit is installed within cupboards or other confined spaces.

Ventilation Controls & Humidity Management

The integrated digital controller enables accurate commissioning and straightforward adjustment of ventilation settings. Compatible humidistat controls can provide demand-based ventilation, increasing airflow when humidity levels rise to help manage moisture and condensation.

The Sentinel Kinetic Plus range also offers humidity-responsive control functionality on appropriately equipped models, including proportional boost and features designed to reduce unnecessary operation caused by gradual overnight humidity changes.

Optional Acoustic Solutions

For noise-sensitive environments, compatible acoustic accessories are available. The optional acoustic enclosure helps reduce noise emitted directly from the unit, while the acoustic top box is designed to reduce noise transmitted through connected ductwork at key frequencies.
