Chlorine Gas Filter

C‑100 Chlorine Gas Filter

Compact, Reliable Chlorine Gas Filtration for Industrial and Municipal Systems

The C‑100 Chlorine Gas Filter is a high-performance filtration unit designed to remove moisture and particulates from chlorine gas lines. Featuring a dual-chamber design, this rugged filter serves both as a liquid trap and a fine particulate filter, helping to safeguard regulators, chlorinators, and downstream components in your gas feed system.

Whether used in a municipal water treatment facility or a high-volume industrial setting, the C‑100 Gas Filter enhances the reliability, safety, and longevity of your chlorination process.

How the C‑100 Gas Filter Works

The C‑100 Chlorine Gas Line Filter is built with a two-stage internal design:

Lower Chamber – Liquid Trap
Incoming chlorine gas slows as it enters the filter, allowing entrained liquid chlorine and ferric chloride residue to settle at the bottom of the chamber. This process prevents moisture from reaching sensitive downstream equipment.
Upper Chamber – Filter Cartridge
Gas then passes through a removable fiberglass cartridge and pad system designed to capture fine particulate matter. The result is a clean, dry chlorine gas supply that supports optimal system function and protects metering valves, feed regulators, and gas feed equipment.

Installation Guidance

To ensure proper operation and maximize protection, install the C‑100 Chlorine Gas Filter as follows:

Immediately after chlorine ton cylinders, bulk evaporators, or supply manifolds
Before any pressure-reducing valves or flow control devices
In a vertical orientation, with enough clearance beneath the filter for pad replacement
Use inline unions or pressurized gas manifolds for easier servicing

The C‑100 Gas Filter is compatible with a variety of chlorination setups, including liquid feed systems and conventional vacuum systems.

Maintenance & Replacement Parts

Maintenance for the C‑100 Chlorine Gas Line Filter is simple and cost-effective. The internal filter cartridge and pads are removable and replaceable, allowing for routine service without specialized tools.

Applications and Industry Use

The C‑100 Chlorine Gas Filter is ideal for use in chlorine gas feed systems across a range of sectors:

Municipal Water Treatment
Removes harmful impurities before gas enters regulators or injection diffusers, improving performance and reliability. Learn more about the top benefits of chlorination for water treatment.
Fruit & Vegetable Processing
Used to maintain purity in chlorine gas systems for post-harvest sanitation and equipment disinfection. See how it’s applied in fruit and vegetable packing facilities.
Pulp & Paper Mills
Protects chlorination equipment from moisture and corrosion in high-demand industrial processes. View more about chlorination use in pulp and paper mills.
Aquatic Facilities and Industrial Pools
Prevents fouling of injection systems and supports accurate dosing when paired with injection diffusers.
Evaporator-Based Gas Systems
Ensures dry chlorine gas reaches downstream gauges, switches, and solenoids for accurate measurement and safe performance.

C‑100 vs. C‑282 Chlorine Gas Filters

While both models provide dual-stage gas purification, the C‑100 Gas Filter offers a compact profile and simplified service for systems where space or access is limited.

Feature	C‑100 Gas Filter	C‑282 Gas Filter
Inlet/Outlet Size	1″ FNPT	1″ FNPT
Filter Model	C‑100I (Insert), C‑100P (Pads)	C‑282I (Insert), C‑282P (Pads)
Max Working Pressure	560 psi	560 psi
Installation Position	Upstream of regulators	Upstream of regulators

Both filters are constructed from high-tensile grey iron and feature interchangeable maintenance parts. If you are unsure which model is best for your system, Hydro Instruments can provide guidance based on your gas source, line configuration, and usage requirements.

Frequently Asked Questions About the C‑100 Chlorine Gas Filter

What does the C‑100 Chlorine Gas Filter do?

The C‑100 Chlorine Gas Filter removes liquid contaminants and particulate matter from chlorine gas lines. It helps ensure clean, dry chlorine reaches your gas feed system, protecting chlorinators, valves, and regulators from corrosion, clogging, and damage.

Where should the C‑100 Gas Filter be installed?

The C‑100 Gas Filter should be installed upstream of any pressure-reducing valves or feed equipment, typically right after the chlorine ton cylinder, evaporator, or supply manifold. For ideal performance, install it vertically with enough clearance for maintenance access.

How is the C‑100 Chlorine Gas Line Filter maintained?

Routine maintenance involves checking and replacing the internal filter insert and filter pads. These components are designed for easy removal and service. For specific maintenance intervals and part numbers, see the official C‑100 Gas Filter product bulletin (PDF) or contact Hydro Instruments directly.

What systems are compatible with the C‑100 Filter?

The C‑100 Chlorine Gas Line Filter integrates easily with both gas feed systems and liquid feed chlorination systems, including conventional vacuum systems. It is especially useful in systems that rely on ton cylinders, evaporators, or bulk chlorine supplies.

What types of contaminants does the C‑100 Filter remove?

The C‑100 Filter is effective at removing entrained liquids like chlorine condensate or ferric chloride, as well as small solid particles. This prevents fouling and damage to sensitive components such as injection diffusers, solenoid valves, and gas regulators.

Can I use the C‑100 in industrial or agricultural settings?

Yes. The C‑100 Gas Filter is well-suited for municipal water systems, industrial processing plants, fruit and vegetable packing operations, and pulp and paper mills. It helps maintain performance across a wide range of chlorine gas applications.

How does the C‑100 compare to the C‑282 Gas Filter?

While both models use similar two-stage filtration principles, the C‑100 Chlorine Gas Filter is a slightly more compact option. Both filters offer interchangeable parts and similar protection, but your choice may depend on system layout or existing equipment. For guidance, contact Hydro Instruments for a recommendation.

Where can I get replacement parts for the C‑100 Filter?

Replacement inserts, filter pads, and gaskets are available directly from Hydro Instruments or authorized distributors. The C‑100 Gas Filter product bulletin includes part numbers and maintenance guidance.
