Below you will find the answers to the questions we get asked the most about our products.
Can Multi-Fuel® filters be used for diesel fuel?

Multi-Fuel filters are not recommended for use with diesel fuel. The utilization of Multi-Fuel filters with diesel fuel may lead to premature water detection.

Does Hydrosorb® remove water from fuel?

While Hydrosorb does remove water from fuel, its primary function is to detect excess water and regulate fuel flow to signal the operator of any abnormal water conditions. Hydrosorb filters are intended to serve as a vigilant water detection alert system.

Do you have a water separator?

We do not currently provide water separator or coalescing filters.

Do you have anyone in my area that sells your filters?

For inquiries regarding local distributors of our filters, please use our distributor locator feature.

Do I need a Centurion or 800 series?

The choice between the Centurion and 800 series filters depends on your installation and operational preferences. Centurion filters provide the convenience of replaceable cartridges but offer fewer options in terms of media and micron selections. We recommend reviewing our catalog to compare differences in adaptor or filter head options to determine the best fit for your needs. Additionally, it's essential to consider the flow rates: The 800 series boasts a maximum flow rate of 40gpm, whereas the Centurion Single has a maximum flow rate of 30gpm, the Centurion Double has a maximum flow rate of 60gpm, and the Centurion Triple has a maximum flow rate of 90gpm.

Why don't you sell the drain valve filters anymore?

The decision to discontinue the sale of drain valve filters stemmed from their similarity to other products within our range, albeit without drain functionality. Amid the COVID pandemic, we prioritized the optimization of available resources, leading us to cease their production. As of now, there are no plans to reintroduce these filters into our product line.

How often should I be changing my filters? What is the expected life of a filter?

The frequency of filter changes should be based on several factors: a noticeable decrease in flow rate through the filter, reaching a differential pressure of 20 psid, or at least annually as a minimum standard. Regular inspections throughout the filter's service life are also recommended. The expected service life of a filter primarily depends on the cleanliness of the fuel it processes.

What micron should I use for diesel fuel?

The micron rating for diesel fuel filtration depends on the specific objectives of your filtration system and any relevant state and local regulations that may apply.

How can I achieve greater than “X” GPM?

To attain flow rates greater than "X" GPM, the optimal approach is to utilize a larger-sized filter or one that offers increased media surface area to minimize flow restriction. Our filters are engineered with maximum flow rates, facilitating the selection process to meet the requirements of specific applications.

How would a Hydrosorb® work with a gravity fed systems?

In a gravity-fed system, a Hydrosorb operates similarly to its functionality in a pressurized system, albeit without the supplementary pressure generated by a pump.

What is the shelf life on a filter?

The shelf life of our filters is covered under our limited warranty policy. For detailed information, please refer to our Limited Warranty page.

Can I mount the filter Horizontally?

Yes, mounting the filter horizontally is permissible. However, it is essential to purge the system of air properly. Additionally, precautions must be taken to prevent leaked fluids or spills when changing a filter.

Do we have a cap for the 400 or 800 Series filters?

We do not offer caps for the 400 or 800 Series filters.

What happens to a Multi-Fuel® filter if it is used with E85?

Utilizing a Multi-Fuel filter with E85 fuel is not advised. The elevated alcohol content in E85 interferes with the filter media's ability to handle any water present in the same manner as it does with E10 fuel. For applications involving E85, please refer to our HA model filters for this purpose.

What filters do you recommend for a gravity fed tank?

Selecting the appropriate filter for a gravity-fed tank involves various considerations. We recommend consulting your distributor for personalized guidance and further information tailored to your specific needs.

Can your filters be used with Kerosene?

Cim-Tek filters are indeed compatible with kerosene. However, it's important to note that kerosene is not recognized under applicable UL dispenser standards.

Explaining ¾” and 1” opening vs 1”-12 thread and 1 ½” – 16 thread?

The ¾” and 1” opening refers to the diameter of the inlet and outlet ports on the filter housing. A 1”-12 thread and 1 ½”-16 thread refer to the threading specifications of the filter's connections. The first number (1” or 1 ½”) indicates the nominal diameter of the thread, while the second number (12 or 16) represents the number of threads per inch. So, the 1”-12 thread has a 1-inch nominal diameter with 12 threads per inch, while the 1 ½”-16 thread has a 1 ½-inch nominal diameter with 16 threads per inch.

Why would you want a 1” opening?

A 1” opening may be preferred for several reasons. A larger opening facilitates a higher flow rate, which is beneficial in applications where processing a greater volume of fuel efficiently is necessary. Some fuel systems may necessitate fittings or hoses with a 1” diameter, making a filter with a corresponding opening size essential for seamless integration and compatibility. Additionally, larger openings contribute to minimizing pressure drop across the filter, ensuring optimal fuel flow and system performance.

What is the difference between a 2, 10 & a 30 Micron?

The difference between a 2, 10, and 30 micron filter lies in the particulate size they are designed to capture. A micron, which is short for micrometer, is a unit of measurement equal to one-thousandth of a millimeter or one-millionth of a meter. In this context, the smaller the micron rating, the finer the filtration. Therefore, a 2 micron filter will capture smaller particles than a 10 micron filter, and a 10 micron filter will capture smaller particles than a 30 micron filter.

Can I install the filter on the suction side of the pump?

Installing the filter on the suction side of the pump is not recommended.

Do you make any filters for aviation?

No, our filters are not designed or intended for use in aviation applications.

At what PSI does the Pre-Vent fill cap relieve pressure?

The Pre-Vent fill cap maintains pressure at approximately 2.5 PSI within the storage tank, effectively preventing vapors from escaping the tank. Additionally, it relieves vacuum pressure to accommodate pump out rates of up to 30 gpm.

Is there a vacuum release on the Pre-Vent fill cap?

Yes, the Pre-Vent fill cap features a vacuum release mechanism. This function enables air to enter the tank as fuel is being pumped out.

How do I find the PSI rating for my filter?

To find the PSI rating for your filter, we recommend referring to our website, our catalog, or contacting your distributor for assistance.
