Ideal For These Situations

Zeogaia solves problems that conventional deodorizers can’t.

Need Low-carbon Equipment

Looking for deodorization that reduces your carbon footprint? Zeogaia’s
ceramic material and zero-electricity operation make it the sustainable choice.

Replacing Activated Carbon / Combustion

Want an alternative to high-cost activated carbon replacement or energy-intensive
combustion systems? Zeogaia delivers comparable performance at lower total cost.

No Utility Lines Available

No water, compressed air, or power supply at the duct location?
Zeogaia requires zero utilities — just install the filter casing on the duct.

Fire / Chemical / Moisture Restrictions

Production lines where flammable materials, chemicals, or water contamination
are prohibited. Zeogaia is non-combustible ceramic — certified per ISO 5660-1.

Mixed Odors & Varying Intensity

Exhaust with multiple odor components and fluctuating intensity levels.
Zeogaia handles complex odors across a wide range of concentrations.

New Factory Planning

Designing a new facility or relocating? Zeogaia integrates easily into
duct design. Demo testing available to validate performance before commitment.

6 Reasons Zeogaia Is Chosen for Factory Exhaust

Wide Odor Coverage

Originally developed for cooking exhaust, Zeogaia is effective against a broad
range of food processing odors. Unlike scrubbers, it handles diverse compounds
without chemical specificity. 75–90% deodorization efficiency demonstrated
in food manufacturing applications.

Lower Carbon Than Alternatives

Ceramic primary material — no high-CO₂ manufacturing process like activated
carbon. Zero electricity consumption during operation — unlike combustion
systems that run continuously.

Zero Utilities Required

No water, electricity, or compressed air needed. The system consists of
filter cassettes in a casing unit installed on the exhaust duct —
nothing else.

Safe for Restricted Lines

Non-combustible inorganic ceramic fiber — certified per ISO 5660-1.
Safe for production lines where flammable materials, chemicals, or
moisture are prohibited.

Adjustable Capacity

Filter layers can be added or removed post-installation to match actual
odor intensity. Start with reserved casing slots and adjust based on
real-world performance and complaint status.

Easy Installation & Maintenance

Thin, square filter format slides into casing units. Open the door,
access filters directly. No utility connections to maintain.
Filter replacement is fast and simple.

How Zeogaia Works

Physical adsorption with intelligent release — no chemicals, no power.

Principle

Physical Adsorption

The Zeogaia filter surface contains countless micro-pores of varying sizes.
Odor molecules are captured (adsorbed) as exhaust air passes through these
pores — a purely physical process with no chemical reactions.

Effect

Multi-compound Deodorization

Multiple deodorizing raw materials optimized for cooking/food odors are blended
into each ceramic filter. Especially effective against burnt/scorched odors —
the primary cause of odor complaints — which activated carbon handles poorly.

Feature

Slow-release Mechanism

During high-odor periods, Zeogaia aggressively adsorbs. When exhaust odor
weakens, adsorbed molecules are gradually released with partial decomposition —
self-regenerating the filter’s capacity for the next peak.

2022 Improved Model

Better performance, smaller footprint, lower cost.

Specification	Previous Model	2022 Improved
Deodorization performance	Baseline	~10% higher
Required layers (90%+ target)	3 layers	2 layers
Pressure loss	~171 Pa / 3 layers	~142 Pa / 2 layers
Standard casing	Max 5-layer (3 installed)	Max 3-layer (2 installed)
Casing depth	Baseline	~18% smaller
Price	Baseline	Lower

The improved filter is the same physical size as the previous model — existing
Zeogaia installations can upgrade by swapping in improved filters during routine maintenance.

Demo Testing — Verify Before You Commit

We test with your actual exhaust to prove performance before full installation.

On-site

Full Demo Test

Our team brings a compact test unit with Zeogaia filters to your factory.
We sample odor before and after the unit, measure odor index using the
official triangle bag method, and provide documented results. Only after
confirming satisfactory performance do we proceed to full-scale installation.

Ship-to-you

“Chibi-Zeo” Rental Service

A compact test unit shipped to your facility via courier. Includes all
sampling tools needed. No specialist visit required — anyone can operate it.
Significantly lower cost than a full on-site demo. Test at your convenience,
then return the unit.

Why Odor Control Equipment Is Required

Legal Obligation

“Offensive odor” is classified as one of the 7 types of pollution under
Japan’s Basic Environment Law. Businesses must comply with odor intensity
regulations under the Offensive Odor Control Law. Failure to comply
can result in administrative inspections and enforcement actions.

Community Relations

Odor complaints from residents can escalate to administrative intervention.
Proactive odor control demonstrates corporate responsibility and maintains
good relationships with surrounding communities.

FAQ

How often does the filter need maintenance?

Maintenance frequency depends on exhaust conditions. Due to the slow-release
self-regeneration mechanism, Zeogaia filters have a longer effective life than
activated carbon. Regular visual inspection is recommended, with filter
replacement based on actual odor performance monitoring.

What deodorization efficiency can I expect?

In food manufacturing applications, 75–90% deodorization efficiency has been
consistently demonstrated. The improved (2022) model achieves 90%+ with just
2 filter layers, compared to 3 layers in the previous model.

What is the pressure loss?

The 2022 improved model has approximately 142 Pa across 2 layers (at 3.0 m/s).
This is lower than the previous model’s 171 Pa across 3 layers, despite delivering
higher deodorization performance.

How do you select the right equipment size?

Selection is based on your exhaust air volume, duct dimensions, odor intensity,
and target outlet level. We typically recommend an on-site demo test or the
Chibi-Zeo rental service to validate performance before sizing the full system.

Can existing Zeogaia users upgrade to the improved filter?

Yes. The 2022 improved filter has the same physical dimensions as the previous
model. Existing installations can upgrade by simply swapping in the new filters
during routine maintenance — no casing modifications needed.
