Key Benefits
- Designed for acid mist and corrosive exhaust, not adapted from general ventilation. The JH-FSP001 is purpose-built for fume hood and chemical exhaust treatment, not a repurposed general-purpose scrubber.
- PP construction survives what metal can’t. The polypropylene body resists chemical attack from continuous acidic and wet exposure, so the equipment treating your exhaust isn’t quietly corroding from the same gas stream it’s meant to neutralize.
- Spray-and-packing design built for absorption. The multi-stage spray section and PP hollow ball packing layer maximize gas-liquid contact time and surface area — the two variables that determine whether a scrubber actually captures acid mist or just passes it through.
- Compact vertical design for real-world installations. The vertical tower footprint reduces the floor or rooftop space needed, which matters when retrofitting exhaust treatment into an existing building.
- Configurable for your specific site and application. You can adjust the water replenishment method, dosing system, pump type, control setup, and body material to match your exhaust conditions and installation requirements.
Why PP Matters in Acid Exhaust Treatment
Acid mist scrubbing only works if the equipment can survive the environment it treats. In wet, acidic exhaust conditions, standard metal housings pit and corrode under the same gases the scrubber is designed to handle. That means a metal unit can look functional while quietly losing structural integrity and surface finish—until it fails.
Polypropylene doesn’t have that vulnerability. It is chemically inert to most acids and doesn’t degrade under continuous contact with acidic mist or moisture. That’s why PP is the standard construction choice for this type of wet scrubber: the body material matches the operating environment.
Beyond material choice, the scrubbing system itself matters. The nozzles distribute liquid evenly across the packing layer, and the multi-sided PP hollow ball media provides a large surface area for gas-liquid contact. That contact determines removal efficiency—not the unit size or the speed of the fan pulling air through it.
For facilities running fume hoods, acid handling stations, or any exhaust point with corrosive gas byproducts, the JH-FSP001 addresses both sides of the problem: a corrosion-resistant body and an absorption system designed to actually capture the contaminants.

Key Features
PP Body (8 mm / 10 mm sheet)
The scrubber body is built from polypropylene sheet at 8 mm or 10 mm thickness, selected for corrosion resistance in continuously wet and acidic operating environments.
Multi-Stage Spray Section
Three rows of spray distribution with nylon ball sprinkle sinks deliver scrubbing liquid across multiple stages, increasing contact between the exhaust gas stream and the treatment liquid.
PP Hollow Ball Packing Layer
Multi-sided PP hollow ball packing media creates the gas-liquid contact surface needed for acid mist absorption. The media layer is housed within the grid panel and is replaced as needed over the unit’s service life.
Circulation Tank and Water Distribution
Manages scrubbing liquid flow through the system and supports continuous spray circulation during operation.
Level Indicator and Dual Inspection Windows
Allows visual monitoring of liquid levels and internal conditions without interrupting operation or opening the unit.
Level Controller and Overflow Outlet
Maintains appropriate liquid levels automatically, with a float-type water cutoff and a dedicated overflow outlet for safe liquid management.
Chemical-Resistant Circulation Pump with Pressure Gauge
Circulates scrubbing liquid through the spray section. The pump is specified for chemical resistance suitable for acidic scrubbing solutions.
Automatic and Manual Water Replenishment
Fresh water replenishment can run automatically on a 24-hour control cycle or be operated manually, depending on site preference.
DELIXI Electrical Control System
DELIXI-brand electrical components control system operation, with manual and automatic control modes.
Optional Automatic Chemical Dosing System
For facilities that require automated addition of neutralizing chemicals, an automatic dosing system can be added to the standard configuration.

Frequently Asked Questions
What exhaust types does the JH-FSP001 treat?
It is designed for acid mist and water-soluble corrosive gases — the type of exhaust generated by fume hoods handling acids, chemical dosing stations, and wet chemistry processes. It uses spray circulation and packing media to bring the exhaust gas into contact with a scrubbing liquid that neutralizes or absorbs the acid content.
Can it connect to a laboratory fume hood exhaust system?
Yes. It is built specifically for fume hood and chemical exhaust applications where acid mist is present, and it is sized and configured to integrate with ducted lab exhaust systems.
Why is PP the standard material for this type of scrubber?
PP resists chemical attack from most acids and doesn’t degrade under continuous wet, acidic exposure — the same conditions that cause ordinary metal equipment to corrode over time. It is the standard material for acid mist scrubbing because the body chemistry matches the operating environment.
Is automatic chemical dosing available?
Yes. You can add an optional automatic dosing system to the standard configuration for facilities that need automated addition of neutralizing chemicals rather than manual dosing.
How do I determine the right scrubber size for my site?
Sizing depends on your airflow volume, inlet gas type and concentration, and installation conditions. Share these details when you request a quote, and our team will help match the configuration to your exhaust system.
How does PP compare to FRP or stainless steel for this application?
PP is the cost-effective standard for most acid mist applications. FRP is an alternative with different structural characteristics suited to certain project or regional requirements. Stainless steel suits applications that require a metal body, but grade selection must match the specific gas stream — not all stainless grades resist acidic exposure equally. Our team can advise on the right material based on your conditions.
What types of facilities use this scrubber?
It is used in chemical and wet chemistry labs, pharmaceutical facilities, educational and research institutions, chemical processing operations, pickling lines, and any facility with fume hood or process exhaust containing acid mist or corrosive gases.
