VentPlus for workplaces

Alert staff.
Enhanced productivity.

Modern offices are sealed for thermal efficiency and noise insulation — and that seal lets CO2 accumulate, silently. VentPlus is India's best CO₂ monitor & controller for offices — a plug-and-play carbon dioxide monitor and automatic ventilation controller. Decisions, meetings and staff comfort all improve when the air does.

The hidden problem in
every full room

In high-occupancy spaces — conference rooms, meeting rooms, restaurants, bars, banquet halls — CO2 surges due to human respiration. Without a CO2 monitor, the rise in CO2 levels progressively causes reduction in alertness, yawning, drowsiness, stuffy feeling, significant cognitive impairment, breathing discomfort, fatigue, headache, and nausea. These elevated and harmful CO2 levels remain completely undetected. A CO₂ monitor on the wall is the first step — VentPlus adds automatic ventilation control on top.

A typical meeting room · 8–12 occupants · door closed

400ppm Excellent Fresh outdoor air. Optimal for productivity and deep sleep.
600ppm Good ASHRAE & WHO recommended range for indoor spaces.
1,000ppm Moderate Reduced alertness, slower decision-making begins.
1,500ppm Poor Yawning, drowsiness.
2,500ppm Very Poor Stuffy feeling, significant cognitive impairment. Avoid prolonged exposure.
4,000ppm Severe Breathing discomfort, fatigue, headache, nausea. The room needs immediate ventilation.
15–50%

Research proves cognitive performance can decline by 15% to 50% at these elevated CO2 levels — directly impacting meeting efficiency and employee output.

> 2,000 ppm Restaurants & bars during peak hours
> 3,000 ppm Banquet halls during large gatherings
60–90 min Time for a full meeting room to reach 2,500 ppm

The VentPlus solution

The best CO₂ monitor for
conference rooms — and beyond

Indoor air quality should never be left to guesswork or inconsistent manual intervention. VentPlus pairs a precise CO2 monitor with a relay to operate your fresh air / exhaust fan / ventilation system — automatically. Plug and play installation — no electrician needed.

1

Continuous monitoring

Real-time CO2 tracking in every monitored space.

2

Automatic activation

Fresh-air intake triggers the moment your set threshold — say 1,000 ppm — is crossed. Mid-meeting, without interruption.

3

Energy optimization

Ventilation shuts down once healthy air — say 800 ppm — is restored. Demand controlled ventilation means HVAC runs only when needed, keeping air-conditioning costs under control.

Proven results

By making indoor air quality both measurable and controllable, VentPlus delivers high-quality environments:

Environmental stability

CO2 maintained consistently below unhealthy levels — even during peak occupancy.

Human impact

Sharpened employee alertness, fewer fatigue-related complaints, and significantly enhanced guest comfort in hospitality venues.

Energy efficiency

HVAC usage optimized through demand-based ventilation — intake systems run only when necessary.
