Pit125 Housing (125MM) – Prima Klima · Modular Base for PitPuk System

The Pit125 Housing (125MM) by Prima Klima is the structural heart of the revolutionary PitPuk modular filtration system, designed to give you total control over the odor elimination in your indoor grow. Unlike traditional static filters, this housing acts as a high-tech skeleton that allows you to customize your filtration capacity based on your crop's needs, ensuring maximum airflow and absolute discretion.

Is your current filter weighing you down?

Let’s be real: wrestling with a heavy, traditional steel carbon filter is a nightmare. A typical session involves awkwardly balancing on a ladder, trying to strap a massive metal cylinder to the roof of your tent without crushing your plants or your back. It takes up valuable vertical space, limits your light height, and frankly, it feels like 1990s technology.

It gets worse when the carbon is exhausted. You have to dismantle the whole heavy rig, throw away a perfectly good steel casing, and buy an entirely new unit. It’s a waste of money, a waste of materials, and a constant source of frustration that makes you dread the maintenance phase of your grow cycle.

The Pit125 Housing changes the game completely. By switching to this modular system, you get a lightweight, aerodynamic base that stays in your grow room for years. You simply snap on the lightweight carbon cartridges (Puks) when needed. It turns a heavy chore into a simple, 2-minute task, giving you more room for your lights and zero stress.

What the Pit125 Housing delivers exactly

This product is the 125mm flange and housing unit required to build a PitPuk filter. It is the foundation upon which you stack your filtration discs.

• Aerodynamic Body: Optimized airflow design to reduce drag on your extractor.
• Impact-Resistant Polyamide: Super tough, non-flammable material that handles heat and bumps easily.
• 125mm Flange: Standard connection for the most common ducting and extractors.
• Modular Base: The starting point to add as many PUK360 cartridges as you need.

How your routine changes from now on

Once you install the Pit125 Housing, you stop worrying about "filter day." Because the housing is made of high-grade polyamide, it is incredibly light compared to metal. You hang it once, and it stays there. When your carbon needs refreshing, you don't take the whole thing down; you just swap the Puk cartridges. It’s like changing a battery instead of buying a new phone.

Your ventilation system will thank you, too. The aerodynamic shape is designed to let air pass through with less resistance than standard filters. This means your extractor fan works less hard, runs quieter, and moves more air, keeping your temperature and humidity perfectly dialed in for those sticky buds.

Advantages and benefits you’ll notice from day one

• Total Modularity: You decide the filtration power. Need more scrubbing for a smelly Sativa? Just stack another Puk on this housing.
• Featherweight: Weighing only 660g, it puts zero stress on your tent bars or pulleys.
• Cost Efficiency: You stop paying for the metal casing every time. You only buy the carbon refill.
• Safety First: The material is self-extinguishing and heat resistant, adding a layer of safety to your grow tents.
• Durability: It doesn't rust, dent, or degrade. It’s a one-time investment for the housing.

Tips to combine it with other Pevgrow products

To get this housing working, you obviously need the carbon. But to truly optimize your stealth setup, you should pair it with the right airflow components. The Pit125 is designed to work seamlessly with high-performance extractors.

• Essential: You must buy the PUK360-3mm activated carbon cartridges to make this functional.
• Ventilation: Pair it with a 125mm Prima Klima extractor for matched airflow dynamics.
• Silence: Since the housing allows for high flow, adding an Extractor Silencer will make your grow room virtually undetectable to the ear.
• Ducting: Use a high-quality Carbon filter for grow tent accessory like soundproof ducting to connect the flange.

Frequently Asked Questions

Does this product include the carbon filter?

No, this is the housing only. You need to purchase the PUK360 activated carbon cartridges separately to filter odors.

Can I use this housing with a 100mm or 150mm extractor?

This specific model has a 125mm flange. You would need a reducer or step-up adapter to fit other sizes, but for best performance, match it with 125mm ducting.

Is it difficult to assemble?

Not at all. It’s designed to be tool-free for the cartridge connection. The parts snap and lock together securely in seconds.

How many cartridges can I stack on this housing?

You can stack multiple cartridges depending on your fan's power. The housing is the base, and you can expand the stack as long as your extractor can pull air through the carbon thickness.

Personal Experience of Pevgrow’s CEO (Alan)

"I've been setting up grow rooms for over a decade, and the shift to modular systems like the PitPuk is one of the smartest moves I've made. I remember the hassle of lugging heavy steel filters up into attic grows—it was a workout I didn't ask for. With the Pit125 Housing, the setup is ridiculously light.

What I really appreciate is the flexibility. If I'm growing a low-odor strain, I use one Puk. If I'm running something super pungent like a Cheese or Diesel, I stack a second cartridge on the same housing without having to buy a whole new filter. It saves me money and space. Just make sure you click the parts together firmly; once it's sealed, it's airtight and bulletproof."
